Hi @Dweomer,
nice game, feels good.
I also want to give a feedback about the limited number of runs before the demo stops.
I take my time to explore the game mechanics and options, thereby i wasn't even in the mines when the demo stopped.
I'd like to have time to explore the game or give me a hint when the demo stops.
Or you could limit the depths of the mines so there is the incentive to buy the game to experience it fully.
I'm interested to see where your game is going :D
