Okay so 2 things for the 1.1 version.
Theres a small bug where any item dropped appears below the floor after entering another room, then disappears when you go through more rooms.
But the glitch you should be paying attention to is falling through the floor. After almost 30 minutes of exploring I entered a completely black room and started falling through the floor, no game over screen, just falling forever. I saved, went to menu screen and loaded the game and it gave me this error message:

please fix this, its preventing people from progressing at all through the game I mean I barely got 30 minutes in.
