First let me welcome you to PGD (even though you've been visiting for a while). Always a pleasure to see a new face around

I have tried your game and I must say it great! Graphics are really nice and sound is even better (imo). Everything seems very well polished.

Some minor things:
:arrow: At the various menuscreens the enter key doesn't seem to work. Perhaps its me, but I tend to use the enter key before spacebar in menus.
:arrow: A fullscreen option may be nice.
:arrow: Instructionscreen isn't working (could be a wip I suppose)
:arrow: Though I personally dont dislike the music, I can understand some people might, so an option to turn if off or at least to decrease/increase the volume, might be good.
:arrow: I find this game much harder than tetris. Probably because a lot of times the items dont match and so a large tower is easily greated. I am not familiar with the origional game, but the room seems small to me. Perhaps its an idea for us newbies to make it larger? (easy/hard mode)

Other than this, its an excellent game!
