Couldn't help but smile, really unique idea, that's well executed. I like the polish of the music speeding up with your speed, and really like your recovery mechanic.
The camera also felt really nice with how it rotated with the player.
I think my only notes is: could you please put the crouch button on space, ctrl + w is a close tab shortcut XD
it would had been nice if you introduced the momentum mechanic earlier on with a smaller hole to teach the player how it works.
anyways well done
