I think the game is fun but it has some flaws.
It's very challenging to make a game look good when you can't actually see anything. Making character's eyes visible was a nice touch though!
I think the controls are a little bit too sensitive. It's difficult to move just one block. Maybe if the character accelerated slowly but not instantly like now, it would let you combine high speed with precision.
The levels felt very repetitive, there was no difficulty curve, but it's probably okay if they're procedurally generated.
