It's Tetris. Tetris is a perfect game.

The developers of this game added some audio and visual bells and whistles to Tetris Effect to make it an interesting experience. While the EDM isn't exactly my thing, the musical effects are quite cool and add an interesting element to the gameplay. The visuals, while very good, can get in the way and distract from the game at hand. It's like they polished a fine marble statue until the glint off of it distracted from the artwork itself.

At the end of the day, it's a stylized version of a perfect game. I can't detract too much from it.
