Cytus vs Osu!
Cytus
Cytus is a fun and challenging, rhythm mobile game that has a rather striking futuristic/sci-fi theme and an intriguing story about how future robots try to save the human emotions they contain from being erased by storing them in the form of music. Cytus is the place where the music will eventually be kept.In terms of gameplay, the controls are easy to learn since there are, at most, 3 types of notes, but there are multiple ways of tapping on those 3 notes. Aside from its intuitive Active Scan Line system, Cytus also features over 200 songs and 400 variations of said songs. However, don't expect to be bip boppin' to the latest hits though. The songs are mostly just music (no singing) and they are often from the dance/electronic genre, though there are some from other genres, like pop, jazz, and trance, too.
Cytus is perhaps the first mobile game of its kind to include a really profound storyline in addition to its incredibly-addictive rhythm-based gameplay. If you're looking for a fun rhythm game for your mobile, this is definitely a game you'll want to play.
Osu!
Osu! is a fun rhythm game reminiscent of the popular Nintendo DS game Elite Beat Agents. However, unlike the game that inspired it, Osu! is completely free to play. In addition to online rankings, replays, as well as chat and multiplayer capabilities, Osu! provides creative players a beatmap editor as well. The selection of available songs is also incredibly extensive, especially with the many player-created beatmaps, allowing the game to persist even long after its launch.This free to play game certainly sets the bars high for any game of its genre so if you love rhythm games, you'll want to play Osu!
