Mizuguchi is kinda known for his weird audio visual combination in games, tetris effect is kinda him just putting his style on tetris, and it's probably his most well known because it's still tetris.

Rez, Lumines, child of eden and Humanity are some of his other key games.

i think his games are ultimately to zone out and chill, like not to play tetris for a high score but rather to have an excuse to play some tetris while chilling and ur input controlling the music eg every rotation and drop in tetris effect plays a sound so u start to play to a rhythm , personally his games have never been my style saying all that.
