This is such a simple idea (and yet not one that would ever have occurred to me!) that you executed so well - the CRT effect is so cool, the UI is beautiful and incomprehensible all at once, the distorted version of the Tetris theme is excellent.
Like others said, the graphical choices added some visual difficulty but honestly that felt very in keeping with the general vibe of the game so I quite liked it.
Great work on your entry!
