Used to play this a few years ago and it was absolutely amazing. But then they changed the price of the characters to hundreds of rings, meaning you have to grind for like 2 weeks to get a single character. For an infinite runner game, that is horrible and just a baffling decision from the devs. No graphics optimization and basically P2W because you need so many rings to unlock one character or to get slots for sprites (basically powerups). Save your time and don't download this.
