I am a big fan of this kind of game (like the ones developed by 1button), and I also worked at gameloft. I liked it, but here's my feedback : > The restart button is not where it should be. I think you should put another screen when you fail, a screen with a back and a restart button. I played for 5 minutes, and it took me a while to not do "back" and "play" instead of hitting "restart directly. > I don't think the color of the bar below is the perfect match for the game. Shoudl be more colorful, with a particular highlight or animation of the "moves" number (so that you understand directly that you have X Moves. > I don't know if there's only 4 levels, but you should put more and most importantly show that there is more. The good example for this one is either 1 button's apps (on/off per example), or TwoDots. Other than that, the game is really cool. Probably gonna try and finish all the levels :) Good work and good luck.
