If you load the game after the credits scene, it returns to the game state before the ending so seeing Wymia on the ground isn't a problem. I take it that you're trying to interact to her without the talk bubble popping up and that's what causing the crashes. I'll see into that.
Yeah, all the scenes in the game have the player in them. The credits scene are just me moving the camera while the player is out of bounds. I actually forgot to freeze the player movement in the scene you mentioned so that's why you can move around, lol.
Thanks for playing the game and for the plenty of bug reports! Really appreciate it!
