And I just cleared the first dungeon, but when I went back to the motel to save, I find that there's an invisible wall blocking the exit, and I can't get out. Luckily I had a different save I could load to salvage my game, but this seems to be a persistent bug. Closing and reopening the game, then playing through the second save to clear the first dungeon still lands me in a motel room with the exit blocked.
...And playing through the second file a third time reveals that I should sleep, except you only get the clue if you try to go into a dungeon other than the one you just cleared. Which is about the last thing I'd do if I just cleared a dungeon and wanted to save after the cutscene.
I guess the game expects us to stumble around talking to bacground props that were unresponsive the first time we explored the area.
I'm especially salty because I crafted a crapton of items before I realized I was trapped the first time, and now I have to do it all over because the game will only tell you you're supposed to be trapped if you don't get trapped in the first place.
