This is a very fun and simple rouge-like game. I especially like how subpar gear is automatically discarded. This saves me a lot of trouble in the long run. Keep up the great work!
Here's how you get potions: After you clear a room, leave it and come back in. The monsters that eat the corpses and the ghosts drop potions regularly (Super-easy to kill). You can keep leaving and re-entering the room for bunches of potions. Have fun!
