Love the hand-drawn aesthetic, the overall vibe, and it's definitely a solid brain teaser.
My critique would be that the platforming could be a little more generous to the player (bigger colliders and more jump power, plus 'coyote-time' air hanging, as some suggestions). This would prevent the frustration of making a small keypress error and having to reset the puzzle back to the state it was at before. Not that that happened to me of course *cough*
Looks like you've got a lot of players rolling in! Don't let any negativity get to you, all those pings. This is a great, complete entry and your team deserves to be proud.
