Kitten Bubble – a ZX Sequel Jam entry


After Ludum Dare Compo disaster, I needed to retake some confidence in my game jam skills. I met Chin during the Zürich two weeks ago and because we both had free time, I proposed him to participate in a random game jam the weekend before Christmas. As I was watching the website, I found the ZX Sequel Jam. It had an interesting theme, doing a sequel of a ZX Spectrum game. For those who don’t know, this is a ZX Spectrum:


The games were on tapes. You put them in, run the Tape Loader program and wait for about ten minutes for the game to be loaded. I had the opportunity to test it in the Zürich gamelab of my school. Of course, the goal of the jam was not to create a game for ZX Spectrum. I wanted something easy that did not required too much of my programming skills. So Chin and I settled for Rainbow Islands a sequel to Bubble Bobble:

So we set up for a mechanic that would combine those from the two games. The main characters were this time transformed into cats, they were throwing bubbles with a bubble thrower, they could enter a bubble and jump again from there and they could put their enemies into bubbles and then jump on them. It looks like this:


I did the simple chiptunes music with Garage Band, some sounds with bfxr and the rest with Unity. Like the GBJam, I had a lot of problem with pixel-perfect, so I finally bought Pixel Perfect that works perfectly for pixel art on Unity 5. I am still a bit pissed off by the fact that it is not native to Unity.

At the end of the weekend, I was happy with the mechanic. The game jam entry is more a proof of concept. Now if we want to go on with this game, we will need to find some long-term motivation to make it work, but I still had a nice weekend.

I lost the game jam

It’s 7:50PM and I’m going home with the train. I was in Thun for the NetGame Convention where I showed Splash, to play-test some features and see how people liked it. In the same time, I was participating at the Ludum Dare 34 in the Compo category. Compo means that you have to make the game all by yourself, code, art, sound, music.

I never did a game jam all by myself. During Nordic Game Jam, I isolated myself, but the assets were done by other people. Here, I’m all alone. The theme were Grow and/or Two Buttons Control. I went on the Two Buttons Controls with a game called “Fat Cat Rock’n’Roll” where you were playing a cat that roll in the snow trying to avoid rocks. A very simple idea, super easy to finish.

So why am I here complaining? I don’t feel the same as with other game jam. I never allowed myself to fail when they were other people involved. I just can abandon someone during a game jam. I abandoned a team before a game jam began, but not during.

Here, if I can stop without any problem. Even if the Ludum Dare community is active on IRC, I feel all alone. I have no social interaction with anyone. The collaborative process is dead to me during the Ludum Dare compo.

I learned something great about myself. I need other people to create. I can not create alone, not because I don’t have the skills, but because I don’t want to. When I’m working on a game, I need someone to ask questions and to work with. My artistic process goes through collaboration.

First I3 game jam, second iteration


What is I3 game jam? It’s a Swiss-French community-based attempt to “commercial” or “In-Studio” game jam. You could see Amnesia Fortnight as a model. Practically, it is 26 Swiss-French Game Developers at the same place working hard on the same game for 45 hours.

I was not invited to the first iteration in July 2015 (like you can see on the picture up there) and I was a bit pissed off at the time. I was not completely known as the extreme game jam hunter like I’m now in the Swiss-French community. Of course, my anger turned off completely when they actually announced the result of this week-end in term of human experience. Managing 26 independent people is a nightmare, worse if you have a game to finish at the end of the week-end.

Communication was one of the main problem. Rumors arose from nowhere, misunderstandings came after it. At the end, the goal to have a game to send for the SwitzerLAN contest was not successful. Indie Game Jams have this notion of equality between the participants. Whenever you worked in the industry or you are a beginner, you own and are represented equally, which sometimes create problems in team that collapsesdirectly, but equality is one of the main rules of indie game jam.

In “In-Studio” game jam like Amnesia Fortnight, there is a clear project chief that can give power to other people, the equality is broken. I3 game jam is between the two concepts. People are voluntary to participate to the game jam, they are not paid like in Double Fine when participating. A leader team have the decisional power, but everyone owns the game at the end and legally, a participant can ask that his work has to be removed from the shown game.

So I was invited to this second iteration, without really knowing what would await me. With my master project on Game Jam it was a fantastic opportunities to see a different way to use the tool that are game jam. To paraphrase David Javet, the Organizer and Project Manager, the I3 Game Jam is platform of meeting and sharing for the game developers.

I was not expecting anything, maybe work on Level Design, maybe code a bit. I arrived there at noon, because I had crunched a bit on Splash with Kevin the day before and I wanted to take the morning for me. David Javet, the project organizer proposes me to be assigned to the gameplay programming team, because one of the original team was missing. I accepted and setup to help my game designer neighbor to learn a bit of Unity, setup some prefabs correctly and finally to install InControl, a Unity plugin that allows cross-platform controllers support, because the game jam game was only supporting Xbox360 controllers on Windows. Quickly as I was going deep in the code, I realized that the InputManager class was not a Singleton, not use in the Menu and all the nightmare you can think about from a code that comes after a game jam. Also, communication with other team members becomes critical. There was a bug with InControl if you had Unity 5.1 compared to Unity 5.2. It meant that developers that did not update to the last version of Unity had a bug with the InControl plugin and was shouting at me, while I was trying to make it work on Unity 5.2. I quickly switch to my own branch, pulling everything from master some times. Finally when it worked I merged it in the master branch and let it go.

I learned several useful lessons on working with a lot of people. Everyone has to be synchronized at the beginning of the event. I think one of the reason the game jam game was not completely successful at it first iteration was that a lot of developers learned Unity during the weekend. I never did a game jam with an unknown engine. I always test the engine before the event. Learning takes to much of precious time that can not be lost. I am going to be the Lead Designer of the second i3 game jam and my approach will be more collaborative. I don’t want to be the only designer in the place saying everyone what he has to do. The second iteration will occur in Fribourg in the first half of next year and I’m looking forward to it.
