Pretty fun for what there is! It took me 8 tries to complete it, partly because in the first few attempts I kept associating space bar with jumping.
Matching the obstacles to the beat of the music is a neat addition.
It's a little strange visually that the enemies move vertically to match the player character. I understand that the point is to require hitting them instead of trying to clear them with jumps, but is that necessary for any reason? I don't think it's inherently bad for the player to have the option to jump enemies.
The slide mechanic looks neat! I couldn't find a use for it aside from cancelling a jump and crashing into obstacles. :)
