I absolutely love this game, but I'm not going to play it ever again because I stopped part way through, and now when I continue I can only use the small rocks. It's a shame that such a small mistake screws up the game so badly.
Oh and Derrick wasn't lying. Read what he says at the end of the comment -
Right click and press play.
It will do a couple of loading screens and stuff then give you that message.
Absolutely love it, but more songs would be great, and (as always), badges wouldn't go unmissed (I know they aren't done by the creator, but you know what I mean)
