For some reason, my mouse sensitivity was at zero when I first launched the game, so I couldn't rotate the camera until I fixed that, and the Options menu is very buggy. Moving between Audio/Game/Controls changed the size of the window, but not the actual list of buttons available. Exiting the Options menu and re-entering did NOT fix this.
At one point, I accidentally started talking to the person in the bathroom stall, which caused a dialog window to appear. But it did NOT disappear after I exited to the menu, or even when I started a new game. I had to completely exit the game and re-launch the .exe to make it go away.
I got in the van, drove a bit, found an underground tunnel hidden under a bunch of wooden boards, and was teleported through the exit. When I came out the other side, I was apparently very very small. I tried climbing on some giant toilet paper rolls, but I got stuck and couldn't move. Some insects appeared on my screen, then I turned off my flashlight and somehow managed to clip under the game world.
Also, pressing Esc brings up the menu, but it doesn't seem to actually stop the game. You can still move around. Is that intentional?
