About This Game

A storm has left the harbor's guiding bells silent. Carrying a tide charm from Grandma Soon-yi, Maru sets out to ring them before the dawn boat returns.

Read the path after your next jump.

Each jump from solid ground advances the tide from low to rising to high. Boats and lifts follow the water, and gates open or close. Reaching the next ledge is only part of the puzzle: think about the tide you will land in.

Cross the harbor from moonlight to dawn.

Pass through jellyfish waterways, a ruined fish market, a flooded warehouse, and a windswept breakwater. Release three locks at the great gate, then venture into the fogbound outer harbor and on to the dawn lighthouse. Eight routes connect the journey, with checkpoints for another attempt when you fall.

Keep a reason to return in your voyage journal.

Find three hidden shells on each route, 24 in all. Improve your best times, meet each route's jump target, and browse the stories and badges you have collected. Unlock 13 pieces of music along the way and listen to them again in the music room.

  • Three tide states that cycle with grounded jumps
  • Eight routes from harbor piers to the great gate and dawn lighthouse
  • 24 shells, route-specific jump targets, and personal best times
  • Route stories, a voyage journal, and a music room
  • Korean and English text, keyboard remapping, and reduced visual effects

Build and share your own route.

Place platforms, gates, enemies and checkpoint flags, preview the tides, and jump straight into a test run. Share your creations as map files and compare local time and jump records for each map. Online rankings and the online map catalogue are not available in this build.
