ABOUT THIS GAME

Sleep Swimmer is a narrative adventure puzzle game where you play as Aria, a teenager escaping the stress of real life by diving into a surreal underwater dream world. In this emotional, character-driven story, you’ll explore the ocean floor, collect sounds, remix music, and solve puzzles that reveal the truth about yourself.

Swim freely through vibrant underwater environments. Help quirky sea creatures like talking salamanders, poetic octopuses, and anxious fish. Reconnect with forgotten friends and use music to calm the chaos around you.

Features

  • Explore a hand-crafted underwater dreamscape filled with secrets

  • Collect sounds from your environment and solve musical puzzles

  • Use your DJ tool, the T.U.N.A., to remix the world and restore harmony

  • Apply effects like echo, reverb, low pass, and solo to shape your music

  • Meet a cast of strange, lovable creatures who remember you better than you remember yourself

  • Uncover a story about pressure, memory, and emotional overwhelm - told through sound

Meet Some of the Gang

The overconfident salamander mayor who’s convinced you can fix everything

A housebound salamander with a fear of the outside world and a pet shrimp named Zeke

Sound-sensitive and stressed, just trying to keep her head above water

A grumpy shopkeeper who’s suspicious of everyone and obsessed with posters

A telepathic riddle-teller who may or may not be from outer space

Make Music with the T.U.N.A.

Your main tool is the Tonal Underwater Note Adjuster, or T.U.N.A. - a DJ system that lets you record and remix sounds found throughout the dream world.

Use effects like:

  • Echo - Repeat sounds to create rhythm or memory

  • Reverb - Soften and stretch sounds to create atmosphere

  • Low Pass - Filter out harsh noise and uncover clarity

  • Solo - Isolate sounds to focus on the details that matter

These tools aren’t just for puzzles - they help Aria communicate, connect, and understand what’s going wrong beneath the waves.
