One of the surprise launches this Tuesday is Dark Tomb, a pocket mint-box dungeon crawler: Dark Tomb. Currently live on KS.
The game features limited exploration (you flip the tiles as you go on) and simple dice-based combat. You just roll a d20, add your weapon modifier, and see if you beat your opponent's armor - if so, you deal damage according to your weapon damage value.
You can choose among different characters, find loot to equip, and battle a variety of monsters.
