This was a first game jam I took part with my Fiancee. We did not plan to do it but during a game jam pre-party we made a spontaniouse decision to give it a try and have fun. That proved to be a very smart move. We managed to deliver the game within not more than 10h.
We made a pinball zombie slasher game where you had to bounce back from exploding zombies and use the momentum to reach another side of the level.
