It's a really good remake of tetris and the dialogue adds to the atmosphere of the game!
Every now and then when I'd try to rotate a block it wouldn't work for some reason, but other than that, the feeling of moving a placing of the blocks was really really good!
I think if you added a small sound effect for when you place a block and another for when you clear a line then it would make the game feel even better!
Really awesome job, the art of the thing invading your mind is also a nice touch!
