Fairly simple platformer that could have benefited from some leniency mechanics. The pixel perfect spikes made some areas a little unfun. Also you should really have credited Celeste for some of the art, since it's clear you've based the character sprite on Madeline, and taken the spikes and Forsaken City tileset directly from the game.
I didn't see a lot of screen transition shenanigans asper the jam limitations, and there were plenty of opportunities between room loads for you to do so.
That said, the wall jumping was fun, and the tree climbing puzzle was clever.
