Those two areas you screenshotted didn't have proper collision blocks placed. The hallway area one is especially nasty because I deliberately took time to check for this bug throughout the area but still missed that place, lol.
The forest area bounds bug is new though. I totally forgot there was piece of flavor text there that I just dragged out of the level to get rid of (oh what you do in a game jam...). By returning to the level from outside the map, you returned to a previous scene from a leftover exit point.
Lol, about the Wymia name. I literally just picked it because it sounded good. Nothing else. Are you Polish? I never could have imagined the word would mean 'udder' in Polish. Tbh, this is pretty hilarious.
Thanks for continuing the bug reports!
