absolutely great!!!
wow, a puzzle game has never hooked me for so long since the days of minesweeper. I've honestly spent hours upon hours playing this game. I've nearly completed every single puzzle (I've only got a couple more to finish on expert and a couple of the downloadable ones). You definitely need to upload some more packs. And seeing as there are some of us who can breeze through the easy, advanced, and most of the expert ones, why don't you add ANOTHER level of difficulty above expert. THAT would definitely keep me busy for awhile. Anyway, very nice game, some of the music was annoying, seriously, I only play the levels while listening to that one drummy loop that sometimes plays ahaha.
Great work dude...
