Unfortunately, it is prototype, and not all functions are ready. Rooms that can be softlocked should have soft reset with long "R" (2sec+). Can you give more info on your situation? Maybe I should use grace period to fix it.
Also, I noticed that you like puzzles. Maybe you would like to try sokoban-like "The Last Spark" on my page? it is couple of years old, but it is far more polished than this one :D
