So, I played this game, and I thought it had tons of potential! This was a really cool and unique game, but I have a few notes!
1) Movement... If you can make a way to press the up arrow and go forward in the direction option that would be great.
2) Frame rate... Im not playing on the best computer, but maybe add a graphics option to try and make it run smoother
3) Game in general... Maybe if this game really becomes successful, you can try and add a story mode for it?
This game is so unique and different, its so fun playing it! You can totally do some next level stuff that no other game has and this could possibly get really famous! Keep up the good work and I look forward to seeing what you do with this!
