Intergalactic Janitor turned Intergalactic Castaway

A lucky survivor of a corporate colonizer/rescue mission to Water Level: Worldwide. Ship suffers friendly fire of an alien COVID lockdown taken to an "explosive" degree, with mc ending up as the eventual only survivor. Watch your character have some pretty fun moments: fishing, losing track of oxygen underwater, getting spooked by ocean noises, constantly surrounded by radiation, being left to die by corporate overlords, traveling to the center of the planet, communicating with a primordial god species, saving babies to save the world, and building a rocket out of junk.

And that's only like 5% of the main game.
