Hi! Unfortunately I've encountered the same bug that made it a bit difficult for me to continue playing. It seems that the character rotation is not locked, so when you push objects sometimes you push yourself (and thus rotate the camera permanently).
Besides that I wasn't sure how the guards attack you. The first one I encountered wasn't moving at all and then I was dead. While that's fine if it's supposed to be a stealth game, I think it could use some visual cues that I've been caught.
Sorry if that sounded harsh, just trying to give some advice :)
