Fun concept, but after multiple playthroughs I still don't understand the game's rules well enough to do any planning. Sometimes doors I was planning to open disappear and I don't know why. Sometimes doors I plan to open disappear at what feels like random. Sometimes I open a lock that's not supposed to destroy my key but it does. I can't predict where the new rooms will appear which matters for using L/R keys.
Showing only one thing changing at a time, and indicating the cause of each of the state changes, would go a long way to helping teach players the rules.
