3 bugs in one

I found 3 bugs in my first few minutes of playing the game, and I'm sorry if some are duplicates, I just wanted to get these out there:

1. Scrolling is very stuttery. This has probably been reported already, but if not, here you go. No video needed, just test for yourselves.

2. Save and Quit to title doesn't make a sound when clicking.

3. Door textures are flipped all the time. See pictures below.
