@lichen in the Electron version, any more details on the door you were stuck at? With more details i could tell you if its a gameplay thing or a bug :P...

Yes, some things are different in the Uxn version. The rooms are in the same order, characters haven't moved either. Only difference is some of the room designs have changes (different tiles, walls, etc). Some of the puzzles have also been tweaked slightly, esp the last one (also new secrets).
