Ratings and reviews

The app improved significantly compared to what I experienced back in 2023 where it was pure greed. Now they improved it, unlocking more songs to choose from plus cheaper subscription. However, the touch detection needs fixing because my touches would be detected halfway through the bars hitting the notes next to what I am supposed to hit. Most of the time my touches would not register in long notes as well.

Terrible UI. No filtering system. Album art usually doesn't match song. Search functionality is annoying to use (e.g., when you choose a song and it turns out not to be the song you want (because, as stated before, album art does not match song title usually), you'll have to search for the song title or song artist when you go back to the song selection screen). Such a shame because the gameplay and songs are really good.

Very very few free music. A far cry from the PC game. But also the clicker thing. I had a clicker installed that I used to auto skip dialogue in certain games, and the game won't run with it just 'installed'? It's not even running? I haven't even used it in months, I forgot I had it. How is that such an issue? But nevermind that, the main issue is the music selection. The subscription is NOT worth it. Only got it for month or two for nostalgia. Other than that the game offers nothing else.
