Osu! is a rhythm game developed by Dean Herbert, initially released in 2007. It is available for Windows, macOS, Android, iOS, and Web Browser. The game involves players using a mouse, keyboard, or touchscreen to match timing and rhythm of tiles that appear on the screen. The main objective of the game is to hit beatmaps in time with the rhythm. The game includes different levels of difficulty and a variety of game modes. Players can compete against other players or against the computer. The game also features a wide range of characters, skins, and soundtracks. Players can also create their own beatmaps and share them with other players. This allows players to customize the game and create unique experiences. The game also includes leaderboards, which rank players based on scores.
StepMania is also a good music game that can be addictive, and it is for desktop computers, unlike most music games.
