Any news? I downloaded the game today and found the same bug on my first time escaping the dungeon. Not a big deal, it just reduced the emotion of winning :-)
I downloaded the Windows 10 64-bit from itch.io yesterday. I don't know how to tell what the last build is. By "escaping the dungeon" I mean win. I recall the game telling me "you've escaped the dungeon" or something like it, when I won a second time.
