The game is very interesting as the gameplay is very cryptic but clearly music based, the graphical style is wonderfull and reminds me a lot of Hylics.
If you like cryptic games, weird visuals, fast-paced rhythm based gameplay with a side of polyrhythms and microtonal tuneings,
than this is the game for you!
