This is one of the worst rhythm games on mobile simply due to the fact that the hit registration sucks. I've lost so many good runs due to tapping in the correct spot but the game seems to think otherwise. I can put up with the tedious grind just to unlock a singe song at random. I can put up with the ridiculously insane $23AUD price wall just to unlock 9 songs, with about half of them being OK at best. But when there's a problem with the core gameplay, why even bother?
