This game was pretty fun!
Like others have said, this concept is really good.
There's a few things holding this game back though, one would be the movement. The player accelerates a bit fast and doesn't seem to cap off at all, making it really hard to control when you're moving for a small ish amount of time, and while you start moving you're really slow and sluggish. The movement overall just felt really sluggish and floaty.
Anyways, the game itself was cool, and the gameplay mechanic was great, well done!
