For the camera bug did you get hit by an enemy into the area transition? I'm unaware of it occurring just from standing, but if you can give more details I can try to figure out what happened.

That's odd... You shouldn't be able to move during screen transitions at all with how it's set up. There's a cutscene flag that disables player input. And now it looks like somehow the build export messed up??? I've replaced the available post jam build, however I'm not sure if that'd help with the camera bug. I'll take a look at it tomorrow if I can figure out what caused it.
