I liked it. I think the visuals work really well, with a nice use of color and backgrounds. The music is very nice too. My favorite thing about this game is that its quite funny. I liked the "AAAA" in the background at the first jump, and the "tiuq" and "yalp" buttons in the menu made me laugh too. The level is nice too, with plenty of intentionally buggy stuff.
The thing I didnt like was that the jump button felt a bit unresponsive for me, and the fact that you couldnt jump while you were walking.
Overall good job!
