I would enjoy this game a lot more if I didn't have to touch every number three to five times before it's excepted! And it's extremely frustrating when I get penalized for taping a number too many times when the game's touch sensitivity is so awful!

I totally love this game, it's absolutely worth the meager $1.99 to get the full/paid version, especially since in the Apple Store the full version has a training mode which make practicing & playing a lot easier & more fun !
