In the end, this is just a tetris clone with a larger playfield and some differently shaped pieces....so, I still can't understand why I find it so addicting and fun! (albeit in a perverse "let's see how some imprevedible pieces can destroy years of automatic responses to tetris")
Nice as always, and the click-instead of drag modify is great, but on the other hand, a bit too similar to the previous versions, and also, maybe a bit too easy
