Plays really smoothly, and already has a solid seed of fun going on. I don't know the roguelike world too well so I don't know what you're up against exactly, or how much this differs from the standard. But I did enjoy myself more than I expected.
The core issue I had was that chests quickly stopped becoming a positive, and started becoming a pain in the ass. This was because the size of my inventory, the rate at which I was using items, and the amount of chests was off. Those three things need to "fit" together, and right now they don't.
