Whether you're new to rhythm-based games or a seasoned pro, Audio Sky is a pretty neat looking addition to the genre, pitting your music against others' in asynchronous PvP multiplayer.
Establish a base on an unknown planet by building up your own song. First you've got to lay down the drum beat by dropping notes on the timeline, before going with other instruments like guitar chords and piano melodies.
You can also visit other people's planets and experience their life-conjuring songs. If you play through them successfully, both you and the host will earn in-game rewards.
Audio Sky will be coming to iOS and Android at the end of 2017/beginning of 2018, and it'll be free to play. Until then, you can sign up to their mailing list here to be one of the first to play.
