This is a pretty good clone, and I appreciate the Colorblind option, though I don't see why something like it couldn't be a default (I do see slight variations in the textures, but it's so samey that I prefer Colorblind mode even though I see colour just fine). My main complaint is I don't see any obvious sort of level selection option, should I quit the game and come back; I have to start over from the beginning to know if I played them all. I do have a small problem with the fact the pieces are not randomized; on one hand, it means every puzzle SHOULD be solvable, but on the other, it's infuriating to realize the developer has DELIBERATELY withheld useful pieces (say, green/heart pieces when the bottommost accessible row is entirely green/hearts) and is basically wasting moves. It is also somewhat sensitive in that if I lift my finger ever so slightly, it will register that as a shot and throw away a move (or two or three!).
