Raising a Turtle with Cannons on its Back

Wave 9, I think? You have to break through to activate auto-attack. They call it an idle game, but there are no offline rewards. It's a very simple game where you upgrade with currency until you meet the conditions to reincarnate, and it's not fun. The in-game currency is scarce, but the upgrade costs are excessive. The rewards are really too small compared to the ad length. The optimization is quite outdated. There's also very little explanation, and attack bugs are frequent. It's a primitive form of idle game.
