OBRUM is a roguelite puzzle game where you operate an unstable system, make impossible decisions, and manage the controlled chaos that is OBRUM. Manage and optimize cores across a 4×4 grid. Trigger them in sequence. Watch values spread, collapse, multiply, mutate, and overload in real time as the board spirals further out of control with every RUN. Every active core increases your score. Every active core also brings you closer to destruction. Push too hard and the system overheats. Play too safely and the system punishes you for it. Draft new Rules between levels. Combine additive, subtractive, and chaotic effects to create devastating chain reactions, destro yenemies, undertake increasingly demanding missions, and survive long enough to reach higher sequences. No two runs evolve the same way. FEATURES Build and execute complex chain reactions Draft powerful and unpredictable Rule combinations Balance score optimization against rising Overcharge Fight enemies that corrupt and manipulate your board Adapt to constantly shifting missions and board states Discover legendary Rule capable of making or breaking entire runs Designed for players who enjoy mastery, experimentation, and high-pressure decision making OBRUM is not about solving a static puzzle. OBRUM is about surviving a system that becomes harder to control the better you get at exploiting it.
