I tried. Got to the hell world and at that point, it felt like a slog to go through and not worth it with so many better challenging games requiring mechanical skill out there. I tried and gave this game a fair shot in my opinion.

Timings sometimes are pixel perfect (i.e. no creativity), unresponsive controls due to lack of buffering or correct input handling, grating music, meh art style, and a ;_; story.

I tried completing earlier levels and gaining bandages, which just asperated my above criticism.

Played the shit out of this game for ~2 years. Diamond perfected > 350 songs + several deluxe versions despite the game's shortcomings. What could've been one of the best rhythm games just to be ruined by shitty monetization.
There's nothing to do after finishing the tour pass (I believe level 22 when I stopped playing) unless you buy the seasonal battlepasses. And then there's the lack luster events that always have the same songs. Getting 100 cards just to open a deluxe box and free gems is a nightmare. You barely get rewarded for playing the game.
Enjoyed the game while I had stuff to unlock for free; not spending a dime. Got boring & repetitive later & honestly grinding this game is not worth it.
