Cut grass, find what was hidden in it, sell that, buy a better blade, cut faster. Grass Rush is an incremental game with the gathering actually played rather than clicked: you walk a world with a tool in hand, the cutting starts when you get close, and the backpack fills until you go and empty it. Six worlds and more than three hundred collectibles down the line, with upgrades to range, speed, luck and carry space, and a rebirth that trades your progress for a permanent bonus.
