Ah rather nice tower defense game. I really love it. The slow downs are bearable considering that most td games even slow down on my desktop. @_wb_ Yes, just finished it.

Framerate drops to less than 10fps when there's more than a handful patients on screen. Also, is it even possible to finish the game? It's very hard to get past level 13 or so. Not a bad game, but feels quite unfinished. Could maybe benefit from notaz' SDL? (if it even uses SDL, I dunno)
