Obrum is a tight roguelite puzzle game where the rules interact, the overcharge builds, and no two runs play the same.
OBRUM is a strategic puzzle roguelite where you build unstable systems, trigger devastating chain reactions, and fight to keep the grid from collapsing.
Draft protocols from three schools:
Growth: amplify and escalate.
Decay: contain and dismantle.
Chaos: unpredictable systems with dangerous rewards.
Every decision shapes the board.
Every run pushes the system closer to overcharge.
Call upon the Helpers of OBRUM when the sequence begins to fail, survive corrupted entities and paradox bosses, and eventually confront OBRUM itself: the intelligence consuming humanity.
