it's actually a really good game. it's much less of a commitment than adom or incursion, but has much more depth than rogue and the like.
it's got fifty levels, five bosses, lots of equipment and items, and decent enemy variation. it has no magic system, but has an alright skills system.
it has also scrapped the hunger mechanic, and gone with a body temperature thing. if you get too cold (or hot :(, as i have), you will die. you maintain your body temperature by wearing clothing that suits the dungeon type, eating, and resting.
