Hotfix: v1.1.1

And of course, as soon as I say development is over, there's a couple of bugs to squash~

In no particular order:

• It is no longer possible to get out of bounds in the treasure chamber or boss room.
• Fullscreen mode has been removed, as it caused endless problems.
• Interior collision has been corrected in some floors.
• The map now gets loaded correctly when restoring from savegame.
• The pronoun thing has been fixed again.
