Framerate loss must have something to do with gamemaker, or maybe its uncompatible with your graphics card. I mean, there are rarely more than 10 objects on the screen....
Fun game if you have the nerve to play 1000th time after you lost. It looks bad. There is a problem with sound if you set it 48000hz or more and on my pc (playing Crysis on max settings) framerate falls on the first stage while running...
I like the diverse "type of mini-games".
Try make it a bit more good looking graphics like Vectorial graphics (it would be nice).
