osu! is a rhythm game based on a DS game called "Elite Beat Agents" and customized by "peppy". The game has a variety of game modes and also a multiplayer function to play with friends. You can download thousands of customized and editable beatmaps that are made by other players so that you can play whatever songs you would like. You can also build your own beatmaps by using its built-in editor! Overall, it's a pretty good rhythm game to pass the time when bored and such.
Gameplay
There are currently 4 playable game modes that osu! has. osu!, Taiko mode (based on the rhythm game "Taiko no Tatsujin"), Catch the Beat, and lastly osu!mania [based on numerous games (ie, Guitar Hero, Beatmania, DJMAX, etc.)].
