Default [GAME][2.3+] Pick the color

Ok guys, this is my first app (in fact my second but the first was like a hello world) so please don't be mean.
This is basically a game where you have to tap the right color very quick.
Try it, like it or not and please leave feedback, I love all feedbacks even if they're negative because it can help me improve myself
