This game is excellent , I look forward to seeing its final form.!
However does it only save progress (after exiting ) in the mobile version?
it save progress automatically after each turn (if you close the game, you'll restart at the same turn). But when you lose, as you probably see it, you restart from the first floor. Later in the game, an object will allow you to restart from the beginning of the current floor.
If you want to try the mobile version, send me a message with your gmail/apple email address.
