You wake up on a brutalist structure rising from an endless ocean.

Run, jump, dodge incoming fire, and fight your way across increasingly dangerous routes. Maintaining momentum is essential: slowing down makes every jump harder, while one mistake can send you into the ocean.

During each run, you can collect upgrades that change your movement, weapons, and chances of survival. The farther you travel, the more hostile and unstable the world becomes.
