Build the board. Set the rules. Survive the collapse.

Welcome to OBRUM, a strategic roguelite puzzle game that challenges your ability to engineer chaos within an unstable system. Forget everything you know about traditional puzzle games; in OBRUM, you are not merely solving static grids—you are orchestrating complex, cascading chain reactions. Every decision you make carries the risk of total system failure, requiring sharp pattern recognition and precise long-term planning to succeed.

Your goal is to manage and optimize individual cores across a dynamic 4x4 grid. You must trigger these cores in specific sequences, watching as values multiply, mutate, and overload in real-time. The board is constantly spiraling out of control, making every roguelite run a unique test of your ability to maintain order amidst growing destruction.

The core tension of the gameplay lies in the high-stakes balancing act of score optimization. Each active core boosts your score, but every action brings you one step closer to a catastrophic system meltdown. Play too aggressively and the board overheats; play too safely and the system will actively punish your stagnation. Between levels, you draft new game-changing rules, allowing you to combine additive, subtractive, and chaotic effects to dominate your enemies and survive increasingly demanding missions.
