I really wanted to like this game, but in the end I gave up in the middle of the campaign. Instead of investing into interesting game modes (such as the "Focus mode" which is kinda cool approach, but it was more like an "extra points" mode rather than a full blown gaming mode), all you get is really distracting visual effects with annoying music / audio FX, while the game speed suddenly jumps from 1 to 8 then 11, all in the same "level". In some levels the speed can actually decrease as you progress, this makes no sense!
Eventually, "practice makes perfect" in Tetris, but to be motivated the players should get coherent and smart gaming experience, rather than this mess. I was "lucky" to get this game for free as part of my Xbox Game Pass subscription, otherwise I would be really upset spending the ~25$ it costs now during Black Friday / Cyber Monday deals.
