Tideglass: Lighthouse Courier

A small boat. A long way home.

The Tideglass archipelago has gone dark. You have a sail, a lantern, and six beacons to restore. Collect every glowing shard in a passage, then sail into the lighthouse ring to bring it back to life.

Each sea introduces a new challenge: sheltered harbors, coral mazes, circling storms, twin islands, ember shoals, and one final lantern. A rechargeable Tailwind dash gives you a burst of speed and a brief shield. Take your time, or chase three stars on every passage.

How to sail

• Keyboard: WASD or arrow keys to sail. Space to dash. Escape or P to pause. Tab and Enter navigate menus.
• Mouse: click and hold the sea to steer toward the pointer. Use the Tailwind button to dash.
• Touch: touch and hold the sea to steer. Tap Tailwind to dash.
• Collect the mint light shards. Avoid islands and red storm buoys. Enter the gold lighthouse ring when your lantern is full.

A voyage that stays with you

Your current passage, collected shards, hull, boat position, unlocked stages, and best medals are saved through Arcadible saves. Come back in the same browser or Arcadible app and choose Continue voyage. Saves survive game updates. Arcadible saves stay on your device and do not sync between browsers or devices.

A star for restoring the beacon, one for a voyage without bumps, and one for beating the passage's target time. Replay any unlocked sea from the chart. There is no countdown and no permanent loss of unlocked progress.

Made for a moment of calm

Original procedural 3D scenery, a warm paper-and-sea palette, soft synthesized music, and no downloads beyond the game. Six compact passages, with optional medals to chase on return visits. Sound can be muted from the harbor or pause screen.
