great
that had to be the best tetris rip off thingy I have ever played.
the guy below me said the background should be clear,but I personally liked the pics of the levels in the background,keep in mind that some of us like it before you listen to that guy and change it.the best thing about this tetris game is when the characters come down the screen and you can make them bust the blocks and eggman when he's near.
the only way I see that you could have made the game better since its tetris is that maybe the music could change every time you get to a new level in the game seeing as how you get different background pics from the sonic games on every level,I can see how that might make the download a bit bigger but it'd be a nice touch if possible.
Great game,best tetris game I ever player,great job.
