Yeah, I will try to fix a few instances of this bug but I won't be able to fix it everywhere. Thanks for letting me know about it!
I think you could fix it "everywhere" by: if the player is still falling after a long time (say, 2 seconds of falling, more than enough to fall from the tallest building to the ground), just automatically let them be able to jump again once. Most of time, being able to jump out is enough to escape the small places you can get glitched/stuck in.
