Grow a Rock is an active incremental destruction game. Tap a tiny pebble bigger, spend ore on upgrades, then roll, jump and slam through things that used to stop you, from acorns to buildings.The 2.0 update adds bosses with three breakable sections. Time your jumps to target different heights, hit glowing weak points for 3x damage, and break lower sections to collapse the parts above. All nine upgrades have five visual stages.The first two areas are free in the browser demo (about 25 minutes). English and Korean are supported, with no ads.
