Solve fast puzzles. Brew a monster wave. Obliterate the city.

You are the ocean. Your only goal is to forge an unstoppable wall of water and see how much of the coast you can wash away.

Every wave throws a rapid sequence of micro-puzzles at you in real time. Read the water, match the rhythm, and execute fast:

  • Rupture the seabed along the fault lines
  • Pull the tides into sync with the moon
  • Steer deep-ocean swells into alignment
  • Hollow out a massive barrel as the water hits the shallows
  • Time the thunderous crash as the wall of water strikes the coast

The cleaner your execution, the more catastrophic the wave becomes. What starts as a surge over beach chairs turns into an ocean-churning titan that tears through piers, flips yachts, snaps bridges, and levels coastal skyscrapers.

Pure chaos. Zero fail screens.

A mistimed puzzle never ends your run—the wave doesn't stop, it just hits a little lighter. Cash in whatever destruction you carved out, upgrade your power, and send in the next surge.

We Need Your Feedback!

This is an early browser prototype in active development, and we are tuning the puzzles, physics, and destruction based entirely on how it feels in your hands. The web version will feel markedly different vs the downloadable where the water is driven on fluid mechanics rather than shape based, for the best experience play the download.

Tell us what you think in the comments:

  • Did the destruction feel satisfying? What was your favorite thing to obliterate?
  • How did the puzzles feel? Did the rhythm feel crisp and intuitive, or did any mechanic feel clunky or frustrating?
  • How far into the city did you manage to push?

Drop any and all feedback, critiques, or ideas below—we read every single comment.
