Fantastic game! You got a really cohesive style & music, and little bits of references and goofy faces sprinkled about.
The gameplay loop is cleverly used, having basically a giant scene that loops around. Having two dimensions to the time loop aspect is super clever too, being able to rewind/forward is pretty common, but using the closing of the loop as a mechanic too is pretty nifty! You also had checkpoints in sections so it never felt too frustrating to mess up and die, plus the death anim is SO ridiculous, you can't be mad at it.
My only gripes are really minor, the controls feel a bit too stiff, but I feel that's intended with being dependant on the loop, using the items to move you around. I also felt the walls/grounds sometimes blended a bit too much with the background, and didn't feel like they'd be tangible at times, but it was maybe me not paying attention too haha.
Overall it's a fun short experience, and it's pretty clean work for such a short time!
