Some addition overhauls were made to the maps (mostly background changes, but 3 rooms required having their doorways relocated to properly align with other rooms).  There is an option to end a game in the map / inventory / pause screen along with an unexplored map after the player has completed the game at least once (as of the latest update).  Hot Room appearance was gone briefly, but that is back, now.  

Hmm, what else...?   I think that covers the updates, for now.  It's incresingly beginning to look like a proper (albeit short) metroidvania-style game.
