I like it, but as others have mentioned the platforming is tricky! Particularly the wall jump mechanic. I would suggest giving a "grace period" to the player for pressing against the wall would make it much easier to get through wall jumping segments where you need to get like 8+ wall jumps in a row. Or design a different style of wall jump, having to alternate direction button so many times while wall jumping is tough. And since it's timed it adds extra stress to that aspect of the game.
You've got good level design and puzzle mechanics here, and nice art.
Great potential for a fun cozy game.
