If you hold the up key while entering room 302 in the hotel the game will freeze and you'll need to close and reopen the game
Are you sure you didn't press enter at some point, hiding the text and thus "freezing" the game?
Nope, doesn't seem like it. I just rebooted my 0.21 save, and it appears that simply holding the up key will freeze the game without needing to press Enter. It's a minor and reasonably avoidable bug, though.
