New version out now. Here's what's improved in 1.1.3:

- Fixed bug in Cathedral Towers Hard room 14099 where it was possible to get stuck if you fell in a certain area.
- Added drag-and-drop support for mansion files, so you can double-click or drag and drop mansion files to open them with the editor or game. See release notes included with the game for details.
- Added Command-arrow keyboard navigation of rooms to the editor, for quick and easy movement between existing rooms.
- Added the game's version number to title screen.
