This game is absolute garbage, after level 5 the levels repeat. If you beat the 5th level you no longer need to upgrade because the last 5 levels are the exact same as levels 1-5. Of course you have to tolerate an ad every 45 seconds to get that far. I played through this game 100% cutting every single blade of grass so believe me when I say this game is dogwater, the factory and farm that you unlock do nothing either so there are 0 new features as you play the game.
