I have completed the entire game (even the DLC), all I can say is that I am more than satisfied! I play this game whenever I can. The levels and music that are introduced in the game are unique, and there is a good challenge for each level. The tutorial stages before the actual level are great for preparing yourself, and the speed trial feature adds an extra challenge for people who have completed the whole game and/or want to challenge themselves. You need this game. (More DLC, pls?)

This game has taken two spinning balls and somehow made it into a simple to learn, but also super complex game! Tapping to the melody of the songs, carefully pick your way through a potential minefield of your own mistakes, or tap fast and throw caution to the winds, trusting your fingers to keep tapping to the beat! This game also really helps you learn new styles of rhythms that you may not have been exposed to. I think I may check the Steam version out soon, for its custom songs.

This is an excellent, mega fun, "quite challenging" game after the first few mercy worlds, to say the least! i like it lot. I find myself twisting into weird contortions desperately attempting to make up for hitting the screen late or early by pounding it to near breakage levels. this doesn't work though must be a bug! hahahaha just kidding.
