I was wondering why every rock i hit kept falling down until i read the instructions xd. But for real this is a really cool concept! I think its really impressive you made something randomly generated. To any players who want tips on getting a high score: spam click rather than hold on rocks in order to get more boost, also wait until you see a good rock before you move your cursor. PS this game made me try rebinding scroll up and down to left click, It doesn't work so don't try it.
