I find the main game immensely fucking boring. Unlike actual Tetris, the amount of variety in shapes is limited per game and there's far less agency in finding the right patterns to keep going. As a result, the gameplay often feels really samey and they don't do anything to make the game more complex or add variety. On the other hand, the puzzle mode is pretty decent and makes good use of 3D imagery and multiplayer can be a pretty good time. A really inconsistent game if nothing else.

Kind of interesting game design but also pretty annoying presentation, it gives me a headache.
