OK so my entry sucks but it was made in 7 hours :D

(I started on a 3d golfing game that was going nowhere so near the end I restarted from scratch)

Currently it's a python source (requires pygame and python (2.5 and 2.6 have been tested) and win32 py2exe executable.

EDIT:
Here's a win32 exe made with py2exe(3MB instead of 30KB but if you don't have python/pygame installed, it could be more convenient)

GAME PLAY: Note I was making the level during the few last minutes of the compo, as a result I totally borked the huge secret room part, if you find its entrance you won't reach it and you'll get stuck, sorry). However the exit is reachable ;)
