Cool game, but..
Like everyone else, I got stuck, on that damned circle! I was able to unlock "Curved", but, yeah, can't get any farther. I tried a simple dot on both of the hard ones and got a high score, buuuut, not quite high enough.
Same thing when I did absolutely nothing! Got a 96.1% on the Curved with that. O_o
Other than that, it was very addictive. Might as well work on the ones I can do. =D
Note: It's hard playing this on a laptop's touch pad. T _ T
