eh...
I got to level 23 when I decided that "okay, this is kind of annoying". Sometimes if you went really high on a spring and then landed back on it, you would di, which defied the point of having a spring. If you went offscreen it was really hard to tell where you are going to land. Also, it's really aggravating getting killed by touvhing the SIDE of a spike. Come on, if you touch a knife on the blunt part you won't hurt yourself. Think of how you could stand on top of the horizontal spikes in the Sonic games. Also, the idea wasn't too original.
