About the game
You are a treasure hunter who fights through a dark castle in 2D combat. Each run is a string of rooms full of monsters, with bosses to beat. You pick up weapons, armour and treasures that change how you attack. When a run ends, the coins you earned buy lasting upgrades at your camp, and then you go again.
Up to four players can team up, online or on one shared screen. Each of you builds your own character from what you find, and the builds work well together. One player can clear a crowd while another lands a big hit. More players also make the fights harder.
Fights are constant, so you spend most of the time dodging and swinging next to each other. It suits a group that likes loot and builds and does not mind facing a boss again with a new setup.
