The popular OSU! project is a set of several cool musical games. Officially, there are four different modifications, and Mania is the most exciting of them all. The key point of this entertainment is to catch the rhythm of the song. In this mode, you will have to tap the notes that are moving along the conveyor. But all your moves should match the beats. You can use up to 18 notes at once. And the best thing is that you can choose any music you like or even download your own songs. Have fun!
