Hey man, just gave this a go. A nice easy system, rules are clear. I made it to the boss and landed 2 hits before it killed me.
If I had any suggestions it would be finding some way to increase the enemy challenge per floor to scale up with you. Once you get a couple of items from the chests you do breeze through each room. Maybe a modifier or 2 just to keep it spicy.
I enjoyed my playthrough though, nice work and thanks for sharing it!
