another "snake" clone where you must crawl around and collect x-mas gifts. the issue with this one is the play control is slow. the gfx and sound are nice, its to bad not as much time was spent on the game engine.
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
