Hey, so I fell through the floor a bunch, then after reloading a few times, I stopped falling. However, I could not move... Possibly stuck in the floor? I'm not sure but it appears to be the same bug that Just_Artur got. Sad that I couldn't play it.

It's disappointing to hear that some people are getting a game breaking bug that prevents them from playing. I'm not sure why it's only happening to some people though. I think it's happening because the player is spawned before the level has finished loading so they fall through the floor or get stuck in the geometry. It's just unfortunate that I wasn't able to fix it before the deadline.
Thank you for giving it a try though.
