Obrum

Obrum is a strategic logic puzzle roguelite about managing an unstable system on a 4×4 grid. You arrange and activate cores, shape their effects with Rules, and try to score while keeping the board from collapsing. Each active core increases your score but also brings you closer to destruction; pushing too hard overheats the system, while playing too safely is also punished.

Manage the board

Trigger cores in sequence and watch their values spread, collapse, multiply, mutate and overload in real time. Enemies can corrupt and manipulate the board, while missions and board states keep shifting. You build chain reactions to destroy enemies and complete increasingly demanding missions, aiming to survive long enough to reach higher levels.

Draft Rules

Between levels, you draft Rules and combine additive, subtractive and chaotic effects. Legendary Rules can make or break a run, and no two runs evolve the same way. The game centers on balancing score optimization against rising Overcharge, while adapting your plans as the system becomes harder to control.
