Here is the link to the Android version of the game. iOS version incoming soon on the App Store.
So I'm pleasantly surprised with this game. I'm running it on a Moto X 2014 and even with the 3D visuals it's running a solid 60fps. The game itself is much better than I expected, and the game doesn't lock you out of harder difficulties (besides Master) like LLSIF used to before the major JP update.
The master charts are kinda heavy on chords, but they make some good use out of the slide note mechanic. Sometimes it feels a little like I'm playing SDVX :V
In short: It's actually fun!
