Nice borrowing game haha really enjoyed it. The mood, and others pointed out, is quite good. On my second try I managed to get a horrible 3:37:65 for the time (GJ on the confetti too btw haha)
I hope you don't mind, but here are some suggestions (just my opinion in the end):
- I found the jump press a bit too unforgiving some times, you know? Coyote time and jump buffering are somethings that could make the controls feel better;
- Adding a squish to the character when jumping is quite a nice touch on a platformer. With a Tween node, doing so is quite easy.
Once again, I hope you don't mind these comments!
