Not as good as version 2.
The Blocks have become WAY too big. I suppose that makes it harder, but I'm not visually challenged, I didn't have a problem playing no. 2 so why have they been made huge? I like the game it was nice. Now I think your trying too hard.
The score thing is nice you could always make the timer descend quicker every 1000 points or something.
Nice music.
But make the blocks smaller, and try reduce the file size, it's massive for what this game is.
