This is an idle game in disguise – War Tortoise Review

When you first play the game, you actually pay attention to what is happening on screen. Once u get so many upgrades, u can literally use the "auto-battle" button, speed up the time, and eat some popcorn as the battlefield around your turtle explodes without you touching the screen. Once you reach a certain point, your turtle is basically invincible and it gets really boring.
