The game calls itself "0.11.0.alpha" but I can't find that in the menu above.

I play the game and enter a house I have built. After that I select "Quit to title" from the menu. The next time I start the game I start on top of the house instead of inside the house.

This seems to happen when the space between the floor and the ceiling where the player stands is two blocks. I haven't tried this in a cave or other spaces that is built by the game and not the player.
