I love this game, but it has been updated about a year

PLEASE TRY THIS GAME! As a fairly seasoned rhythm gamer, this left me with very good first impressions! The story is okay, but the actual gameplay is so fun. The charts may or may not cycle through a bunch of different modes, like typical top-down, WACCA style, polyrhythm style and more... and I found myself playing this game for 3 hours straight because the charting was so creative. Another thing is that (other than the regular tap notes) you don't need to lift you finger up to hit the rest of the notes, it just needs to be where the note will hit the judgement line which saves a lot of runs and stamina. The art is also incredible.
