First of all, I wasn't expecting so much change in the gameplay by the addition of an extra thruster. It really brings a new curve in the difficulty and opening a lot of gates for the 'WoW' moment. With some really good aesthetic design I think this game will hit the market. In terms of aesthetic design you should check out my game 'Platris'. As we have done a small amount of work (like the camera shakes) but bringing in a strong emotion of satisfaction.
