Very fun game with a charming artstyle, albeit it can be hard for me to discern whats going on at times due to the relatively low contrast of the art
The difficulty curve was not very consistent from start to finish, some of the levels were exceptionally difficult but followed by relatively simple or easy ones.
Once I reached room 15 I almost became hard-stuck and gave up due to some weird control issues I had encountered. When you preform an input, that input will be performed repeatedly as long as you continue holding it down and it's the last input you pressed. For example, if you stand still and hold the jump button, you will constantly bhop until you press another button. The reason I discovered this on room 15 is because I was under the impression holding the jump button would make me jump higher, but what ended up happening was the instant i touched the wall on the right, i was walljumping into the spikes, which lead me to believe the jump was impossible. This was happening on the keyboard arrow-keys control scheme.
One thing i'd suggest is adding a tiny grace period for wall jumps, i often found myself wanting to move away from the wall and then pressing jump after i turn around, but this doesn't work as you aren't against the wall anymore. Might just be because I'm used to that input for walljumps from super metroid and my own game, though. Didn't prove to be a tremendous issue
I finished the game on easy mode, forget how many deaths
