This is my first global game jam game and I'm quite happy with it. We made this game with 5 developers. I did all the programming and the other developes did the art.
The theme was: "transmission". We decided on making a game about the transmission of a disease. You play as a plague doctor and you have to kill as many rats while keeping the people alive. The rats infect the people with a disease and infected people can also infect other people.
I had very little time to program this game so it's not very polished. The player can not strafe and always looks at the mouse. The shooting mechanics don't work that well either. But for a first game jam I think that we achieved a decent result.
