The Greenening Wash the ash, grow the green

The whole planet sits under a layer of ash, and your rain is the only thing that clears it. Drag your cloud across the surface, drop water on the grey, and watch colour and plants surface where the ash washes away. You are not watching numbers tick up on a screen: the difference you make is right there, green spreading over grey. Each area hides things to discover underneath, so every pass of rain can reveal something new. It is the same quiet pleasure as a cleaning video, except you are the one holding the hose, and the mess is an entire buried world.

Every run earns you resources, and resources buy upgrades: stronger rain, better reach, new abilities for your little cloud. The tree is generous, and progression is judged well: you unlock several upgrades most runs, so there is always something a few drops away. As your cloud grows more capable, the ash grows denser and new mechanics and obstacles appear, so the loop keeps shifting without ever turning hostile. There is no prestige system and no reset to grind through. You just get steadily better at the one thing you do, until the last grey patch gives up.

Between cleaning runs you come home to a spaceship, and on that spaceship you grow a garden. Gathered resources feed it, and it becomes your cozy little corner of the game: something green and alive that is entirely yours, tended at your own pace. There is also a collection of objects to find and fill out as you explore, so the world under the ash rewards a curious eye. Cleaning a planet and keeping a garden going turn out to be the same hobby at two different scales.
