This is a game that I wrote during a 24 hour code blitz competition. It got third. My theme was chapulas. It is your basic side scroller. I used only Windows API calls, once again, instead of employing DirectX or OpenGL. It is, um, a little fun to play i guess. I never got to implementing AI, so you just jump through the levels avoiding minor nuisances like water, lava, and spikes.
