If you have any sense of rhythm, don't play! – Tappy Cat - Rhythm Collector Review

The rhythm in this game is terribly bugged. Being a good musician or having a sense of rhythm is actually a downfall in this game. Love the premise, but downloading is a waste of time until they fix an issue where the "perfect" score makes the whole song off beat, or implement settings like Deemo where you can adjust the timing to your phone or headset for accurate gameplay.
