I'm totally late on the draw, but I've got enough of the game working to have confidence that I'll actually have time to finish it.
So! That said, my game is Fishing for Parasites, a game about using an endoscope to 'fish' for parasites in your patient's GI tract. Guide the endoscope using the keyboard keys. Touch the sides of his or her insides and DEAD. Double back on your endoscopic cable and DEAD. In true arcade game fashion, things get faster as you keep playing, and the parasites go deeper and deeper into the intestines.
I should have some screens and/or a fully playable game within the next day or so.
From a technical perspective, I decided to take the slightly weirdo move of using Processing to code the game since it's super easy to prototype in (and just fun to use in general).
