Someone else reported that bug to me in discord as well. I cannot replicate it after like 20 minutes of trying. Although, that's not as bad as the other bug pointed out where the check for the floor is too late for input - so you can literally just hold the keys and go "anywhere" hahaha.
I appreciate the praise on polish! I ended up taking the "lets try every mechanic" test level, and turning it into the tutorial - glad people find it useful.
