bpb game jam 2018: Hugs & Kisses

Just like in 2016, we were invited to a local game jam in Remscheid, Germany, hosted by the bpb (the German Federal Center for Political Education) to make a political statements through game concepts and prototypes. As such, the theme was a bit different than the usual jams: "Discimination, ostracism, radicalization".

Our own entry is a bit more game-y then we would have wanted; but after not being able to find a more meaningful idea (and message) for nearly half a day, we went with one of the earliest concepts we had. So we created a 2-player co-op game about cats and dogs, and about working together to keep all the citizens happy. We called it Hugs & Kisses.

The world map is divided in three zones. The dogs' zone (blue), the cats' zone (red) and the neutral zone between them. In the dog country are mostly dogs and only a few cats, and vice-versa. The neutral zone has both species equally. The gameplay is simple (and inspired by Overcooked): you have to feed the cats and dogs in your country, otherwise they get unhappy. So if there's a cat in cat land craving for fish, the cat player goes to the fish spawning point and carries the fish to the hungry cat.

Only when there is a cat in dog land asking for fish it gets interesting, because a player cannot enter the other player's zone, so they have to work together and trade the fishes and bones with each other by throwing them around.

And sometimes, a community member gets sad and needs to be hugged. <3

In any case, should the needs of a citizen get ignored for too long, they become mad - i.e. they explode and take parts of the level geometry with them. Discrimination has a fatal impact in this case indeed.

You can try our little jam game on itch.io (Windows only). It's best played with two gamepads, but keyboard is fine too. Be aware that it really is a prototype, so there is no real lose or win condition. But see if you can beat the game without anybody blowing up!

By the way, if you are interested in the development of games, you might want to read a short article about Hugs & Kisses on my own blog - it mostly describes the process of creating the level for the game.

Of course it was also very nice to meet many teams from all over Germany and Austria at the jam, seeing their games come to existence during the three days, and of course having a good time together. If you want to find out more about them and their games (and speak a bit of German), click your way through the bpb game jam wiki and have a look at their projects!

Global Game Jam 2017 – Post Mortem

Global Game Jam 2017 - Hands Off Thief

Be aware that YouTube videos try to set cookies and contact Third Party servers!

In January 2017 Jana and I were part of the Global Game Jam, as usual. We had some doubts we'd do it again in Leipzig, because every year it gets a bit harder to wake up in the HTWK (the university where the jam site is located) without a shower or hot water at all. Yes, we're getting older. Our plans went back and forth between not going at all, or driving back home for the nights, or getting an AirBnB. In the end we did it as always.

Thankfully! Commodations aside, it was a very nice experience. A few days before we made some key decision for our jam entry, especially the choice of target platform: VR. As we don't own a full-blown HTC Vive or so, we made a Google Cardboard game for Android. I think it turned out quite well, because it was doable in the scope we aimed for, even though it was our first VR game.

The theme itself ("Waves") wasn't very interesting, but it slowly formed the direction of our game. When we began to think in terms of sound waves, we soon decided that some radio in our game would tell the player what to do. So you'd be in some kind of labyrinth, trying to find that radio by searching around and listening to its noise, and then activate it, because it tells you how to reach the exit. This became less important later, but it's still in the game. So while we don't feature "waves" promintently, the game was definitely inspired by it.

What we have now is an atmospheric stealth game where you play some thief or treasure hunter in a haunted mansion. You walk around, steal things (mostly valuables), evade scary ghosts, use keys, and find the radio and the exit. As the game is a Virtual Reality game, the player's movement is restricted to gliding between square floor tiles in cardinal directions. This is very similar to my Ludum Dare entry Wood for the Trees from last year, but this time the limitation was imposed to us because of the nature of VR games. Free movement was out of question, and a typical "magically beam to place" approach could have been a bit too complex for our first 48 hours VR game. In the end, the limited movement also helped to define the simple but effective behaviour of the evil ghosts, which don't follow you but patrol between the rooms in the same manner as the player.

As usually our games have a somewhat high entry barrier, one of our goals was to simplify controls. With a VR game this seemed easy to do - you don't have much different input methods anyway. All you can do in our jam entry is looking around and take stuff by looking at it for a short time, which is why Jana had the idea to name it Hands Off Thief, as you steal without using your hands... Initially I planned to have the same approach for walking around the rooms - an arrow on the floor tells you if you're allowed to walk into that direction you're looking, and if so, looking at the arrow for a short time moves you to the next room. But it turned out that this is a bit awkward, as you'd always have to look down to walk around. Now players have to activate the trigger (i.e. touch the screen of their phone) when the arrow is shown, which feels a bit more natural.

I prepared by reading articles about VR development for mobile platforms. It was helpful to know that there are some heavy restrictions regarding drawcalls and polycount in order to maintain 60 frames per seconds on a phone. This way I wouldn't be surprised by bad performance at the end of the jam. Thus, from the beginning the Unity project was set up to use cheap vertex lighting, and I programmed a simple occlusion culling i.e. only the room you're in and adjacent rooms get rendered. We also tried to minimize the amount of different materials for everything.

The first thing we did when we started the development was trying to find out how big the virtual rooms should be. Several hours went into discussions if the walls are too near or too far away, if the ceiling is too low, or if the texture scale on the floor is okay. Probably not everything makes sense in the final game; some things were kept for the atmosphere. Especially the lighting was a bit of a headache, until we went with strong darkness and the player having a point light at their center. Every ghost has two lights - on for his current position, and one for the target position. This way, a player can predict if the ghost soon will be floating towards them. And from time to time a lightning strikes (even when there's no window), so there should be enough to see anyway.

Of course we had some help! When he wasn't sleeping Björn Grunewald created some 3D models like the loot, and my brother Ludwig 'KingLudi' Hanisch - as usual - agreed to compose the music. Ludwig was in another city, and when I sent him some screenshots it was very late, so I wasn't sure if he was still willing to do it. But he sent a nice track in time. Afterwards he wasn't content with it, as it didn't quite play along with the visuals. The problem was that Jana and I were late in defining the atmosphere and couldn't send him a meaningful video, so he only had the screenshots with bad lighting as reference. A few days later Ludwig sent us a new, much more eerie track which fit perfectly, and I updated the game. You can play this new and better version by downloading the APK on itch.io.

Overall the Global Game Jam was cool; you might also want to have a look at the other games created at our site in Leipzig. By the way, one aspect I learned to dislike about the GGJ website is that you cannot edit your entry afterwards. I understand that they wouldn't want people to fake their entries, but it would be nice to be able to offer patches, or just add stuff you forgot.

We also might choose to register a jam site in our own city next year, because we found some potential co-jammers!

The bpb:game jam 2016

At the first weekend of August 2016 we once again visited Berlin in order to take part in a game jam hosted by the bpb, the Federal Agency for Civic Education. It was a special jam for us, as we were actually invited by the organizers, and the theme was a lot more serious than we're used to: "Flucht und Vertreibung" (Escape and Eviction).  We didn't really know what to expect, other than that travel expenses, hotel and food would all be paid by the German tax payer. (Thank you all!)

The whole event went from Friday till Sunday, with Friday being reserved for an unconference. It started with everybody introducing themselves, which took a lot of time as there were over 50 people! We knew some of the participants already: they were fellow indie developers. Nonetheless the introductions were very interesting, because - and this is another uncommon thing for our jam trips - around half of the people weren't game developers, but came from various fields, mostly pedagogics. The youngest participant was 16 years old, and I dare not to estimate the age of the oldest person in our group.
The only gripe was the pretty low ratio women to men. Unfortunately this is common, but at least it was higher than at most game jams.

The more interactive part of the unconference were the 'sessions', where people suggested various discussion topics, all in accordance to the main theme, and then do group debates. I suggested "Sprachbarrieren" (language barriers), and thus a few of the participants, including Jana and I, talked about apps for language learning and our experiences with different languages, and how we could use these as gameplay mechanics.

The second session for us was about "Perspektivwechsel" (switching perspective), and here the discussion started with the split-screen camera technique in multiplayer games, but soon got more serious and went from the literal interpretation of perspective to empathy, and how we see others, and games that actually let us "live" different roles; consciously or subconsciously.

Overall these debates prepared us well to get into a more serious mindset, as right afterwards we got instructed to come up with game ideas and discuss them in random groups. I still think the idea of a "Refugee Go", maybe a tad cynical, would be an interesting take on the location-based gaming: the idea was to force the player to literally walk at different places in a real city where they have to fill out virtual forms (in real-time, i.e. with a lot of waiting). The idea was to let players empathize with a refugee in Germany who tries to apply for asylum. As you'd play it with a smartphone only which then demands permanent attention, it would also be a bit like Tamagotchi.

It was new to Jana and me to not discuss our ideas directly with each other, but alas, Jana was in another group. There she formulated the concept of a card game with instructions on each card for the players, and they'd have to run around and solve the tasks.

In the end we found together again. After a few years of jams we became a solid team and apart from a small collaboration now and then we somehow became unable to try new constellations. ;) Some lively discussions later about what our jam entry should be, we settled for a compromise we were actually both happy with: "Visa Runners", later named "Die Stimmung kippt!" (The mood shifts!).

Visa Runners is the prototype for a multiplayer mobile game with real-world interaction, a bit inspired by Space Team. At the beginning all the players connect their smartphones with each other. Afterwards everyone gets assigned a randomly chosen profile of a refugee-seeking person, with character traits like gender, age, birthplace, skin colour, education, etc.

Visa Runner Profiles
Then the real game begins.

The players have to flee to safe countries and get a visa as fast as possible. The countries are represented by QR codes lying around in the (preferably big) room, on tables and maybe even hanging on the walls. In order to get a visa you have to run to the QR code and scan it with your phone. Then you get a few days of visa - so you need to renew this visa very soon and very often. (A "day" is a second long in our game.) To make it harder players get a day less each time they try to seek refuge in the same country. If you overstayed your visa you need to get a new one as soon as possible, because you lose if you're without shelter for too long.


Yes, the game gets unfair quickly. Intentionally so.

To underline this, every few seconds a tabloid issue appears on one of the phones - usually it's a (mildly) exaggerated headline about refugees or foreigners in general. These headlines affect all players, so the one who sees it has to tell the others (or can choose not to). For example, if there are news about "black men attacking a puppy" all players with the traits "dark skin" or "male" will get minus points in that country (i.e. less days of visa). At some point, a country will refuse visas to certain persons, and those have to flee to other countries.HeadlineThe game ends when only one person is left.

Here's hoping we made a game that captured the theme of the jam. I wish the end result were more functional, but for a prototype it worked pretty well. The funny thing is: when we presented our game, it dawned on us that we didn't even need the prototype, as we were only running around with our Android phones, yelling what we're doing currently. It could have been a theatre play...

The first day of actually programming the game was hell, as I had to download the Android SDK first (to be able to actually build games for smartphones), then try to get a certain plug-in from the Unity Asset Store running. It was very badly documented, and I needed hours to find out how it actually works. But after that we finally got the multiplayer part running, and implementing the gameplay was easy enough. Thankfully the plug-in for the QR code scanning was much less of a hassle.

We were very impressed by the games of the other groups, some of them had a team size of five or even more. You can find (German) descriptions of most of the entries at the official wiki - ours is here, even with a downloadable APK.

Overall the first "bpb:game jam" was a success for us, and we think it also was a success as an event. Thanks to the bpb for organizing it! Here's hoping we will be able to take part again next year.
