How do you modernize an icon like Tetris? Simple: You leave the mechanics alone!
Tetris Effectis the same perfect puzzling we know and love, but so much care has gone into enhancing every other facet of the experience. It's Tetrisby way of the folks responsible for games like Luminesand Rez Infinite. In short, it's beautiful. Every single level has its own finely-tuned visual theme, sound effects, and music, and all of those elements exist solely to put you in your own little zen world.
I knew Tetris Effect would be good, but I vastly underestimated just how engrossing it could be.
