Thanks, really nice to hear people like the concept. I also really enjoyed my time when debugging / testing my game.
I agree that there is a lot room to grow (no pun intended). I dabbled with the puzzle-idea, but I enjoy the idea of random rooms better. But balancing them is a bit harder, for sure.
The hero-intention is now very simple: he choses randomly between the available doors (except the door he just came through) ... and if there are no other options, he will backtrack through the door he just came through. But it's all random now. I wanted to make it that the hero would prefer an unvisited room, but didn't had the time to do so anymore ^^
The thing is that in my mind you (the dungeon master) will have to find the right balance between killing monsters ( more points) and grabbing health or only take the safe-route with coins and treasure.
