No revenue estimate for EPIC — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $378 — a different platform, not this one.

The Kaiyo Mission

Control a submarine or a diver into the depths of unknown underwater worlds and take photographs of alien animals, plants and artefacts. Continue your journey through this casual, side-scroller, exploration game and unlock more secrets before travelling to an alien home planet.
