About This Game

Become your very own little rock and do absolutely nothing — together. SSO is a cozy online hangout where you sit, roll, and relax with friends while the weather drifts by, birds land on your head, and moss slowly takes over.

What's new in v0.2 — the Social Update

  • Voice chat — push-to-talk (V) or open mic. Voices come from each rock in 3D, so whispers stay close.
  • Text chat & emotes — speech bubbles, jumps, high fives, and shaking off your moss.
  • Shared drawing board — doodle on a big chalkboard with everyone in the room, live.
  • Study corner — a real-clock Pomodoro circle (25 min focus / 5 min break) so every room studies on the same beat.
  • Birds — stay still long enough and up to three birds will perch on you. Move, and they scatter.
  • Steam friends — invite friends or join them straight from the Steam overlay.

A living rock

  • Moss grows (faster at night), spreads between neighbours, and turns with the real seasons.
  • Fireflies at night, a pond that washes you clean or polishes you into a pebble.
  • Stack up with friends to build cairns.
  • Photo mode to capture the moment.

Make it yours

  • 29 levels and a whole quarry of rock shapes — from skipping stones and geodes to Moai and Dol Hareubang statues.
  • Paint your rock with a full brush, fill, eyedropper and undo toolkit.
  • 24 Steam achievements.

Available in English, Korean and Japanese.
