Is floor 2, room 11 (ghost) the furthest you can go? Good game feel. Unless I missed a door to go further and complete the story line, the experience doesn't feel complete. Definitely solid mechanics in play as well as cohesive art/music.
the room number wasn't supposed to be on screen, it should be fixed now, so thanks for that! :P
and without spoiling too much: on the second level, there is definitely another creature that you should interact with that allows to continue!
