reminds me, I was gonna mention that your walljump tutorial animation might benefit from having onscreen arrow commands. took me a bit to realize I have to continue holding left or right while hitting up even while I'm in the air for it to work consistently. it's kind of an awkward setup, honestly.
edit: if you read what was here before, never mind. instead I discovered my initial assumption was correct and there's a bug that lets you wall jump in the first level without holding the left or right arrow keys.
