Crablike

Crablike is a traditional dungeon-crawler roguelike, following in the footsteps of the original Rogue, where you play as a crab. The whole game takes place underwater, as you travel across the ocean to find the source of a mysterious corruption that is turning all sea life against each other. Do you have the cunning, strategy, and tenacity to survive in the hostile depths?

Of course you do. You're a crab. The pinnacle of evolution.
