That was so fun!! The sprites and the animations were adorable! I especially liked the falling animations after you hit the peak of your jump :)
Also the gameplay was just the right amount of challenging both in platforming and in puzzles. Had a fun time solving the puzzles as well as pulling them off! Also I will admit that I did die a few times before I made it through a lot of the rooms haha.
For the platforming itself, one suggestion I have is to the make jump take a little bit longer to cancel when you let go of the jump button. Though it let's you stop on a dime (if you can stop on a dime in midair that is haha), it can feel a little jerky at times.
Seriously though, the assets were beautiful, and I had a really good time playing it! Would be interested in playing more levels if you got the chance to make more :)
If you get the chance to play it, I would definitely be interested in hearing any sort of feedback on the gameplay, audio, or visuals of the game I submitted. Also, seeing how good your visuals are, if you have any tips on making quality pixel art, I would love to hear it as I'm just starting haha
