This game is great. The runs are relatively short, a full run only takes 20-30 minutes; and the individual fights are only a few minutes long, so it’s perfect for a mobile game. It seems simple but as you unlock the characters each one is more complex, and then each character has a bunch of challenges that pretty heavily change how they work again, so there’s more content than meets the eye.

My only annoyance is there’s no save file system. They get around it by just letting you unlock whatever you want in the menu, which is an ok but not perfect solution.

There’s also a web based demo if you need sold on it. I don’t know if it works well on phones, but the game itself runs great.
