My score was 592 when I quit the game, so I guess that tells a lot on how good it is (it's good).
Took me a while to "get it" but now I kind of feel I could go on forever. It's a really nice "puzzly" match 3 game. Good job!
Thanks.
I realized I didn't even had time to sit and try to have a highscore. I will try later to beat yours :p
