I used to have a variation of this on my old Pocket PC and I played it for hours, so I'm super glad for this to come to Zune. Played it once and my high score was 1496, but someone really should pick up this game and make it better (I would if I could, but I don't know how to code). A few things:
-Music is obviously a must, it's cool without it but the purpose of playing it on an mp3 player is sort of defeated without music. I'd say if the shuffle and playlist features could be added, that'd even be enough.
-High score table of course
-A menu
-Maybe the possibility to scroll by swiping if you want (option in a menu or something) because as it is it takes a while to get from one side of the board to another.
-Change up the game modes some. The version I used to play had 3: This one, which was called Shift; Standard, which makes the blocks stay in place instead of moving across the screen when there's empty space; Continuous, which leaves everything in place and then when there's a whole empty row, all the blocks to the left move over a row and a new row comes in from the left (my favorite).
If most of this is added, this'll definitely be my favorite game on the Zune.
