I made a game about a little rock that can't even beat an acorn. A few upgrades later, it's rolling through cars and buildings.

Grow a Rock is a pixel-art incremental destruction game. Tap to make your rock heavier, spend ore on upgrades, then see how much of the next area you can smash. When something stops you, you can jump over it and slam down on it. Beating an area's boss opens the next one.
Play the free browser demo on itch.io
The demo includes the first two areas. No installation or account needed. The full game is available separately for $2.99, and you can carry your progress over using Settings → Copy save / Paste save.
English and Korean supported. No ads.
I'd love to hear which obstacle stopped you first and whether the growth feels satisfying.
Update (Oct 22): bosses in every area now loom huge until your rock outgrows them, plus jump and collision fixes. Details in the devlog.
