impressions:
+ simple, but fun
+ patterns seem reasonably synched with the music
+ if you like Harmonix house bands, you get like 7 tracks with the game
/ button tapping is good, but wheel tracking is difficult cause the iPod wheel kinda sucks
- you have to create a "Phase Playlist" which is BULLSHIT, I should be able to just pick fucking songs from my library. HELLO YOUR GAME IS ON AN IPOD.
overall, if you like procedural music games like Vib Ribbon you could do a lot worse for $5. That minus is kind of stupid, though.
