A very fun and addictive idea, but as some users have mentioned in the comments, the responsiveness of the controls are dreadfully bad. You have to change directions a split second in advance, not a set distance in advance. So when the character speed picks up, you'll likely way overshoot your inputs. There's also no input buffer, so if you press a button, then press a second button too soon, the second input won't register. It's frustratingly bad and ruins the experience. Fix those things and you have a 5 star game.
