Overall the game is nice and the concept very intersting ! As everyone else said, the controls are heavy and not very responsive ^^.
I saw your reply to another post and yes you should have trusted you more. You can quite easily make a simple controller that works fine. Even if you don't have all the features that you want, at least you know what you're doing and you can improve it bit by bit without breaking the whole thing ;)
But great job overall, the game is great beside that, nice art and music too :D
