I just love that music, please tell me its name :)

It's called "Heroic Return", written by Chris Haigh

It's very hard to find :S i can't get it

What about put the same music here on the site? I'd like to hear it when playing the game. Sure you can activate or deactivate it

I'd demand an option in the settings to be able to permanently turn the music off, personally.
It's not bad music, but when I want music, I put up my own, generally.

I do plan to bring it to the main site, but I don't want to stick it in the .swf since it's so large. I want to see if I can dynamically load it only for the players who turn it on. It's on my list but not a high priority at the moment. You can always just open the Kongregate version in a background tab :)

Can I get the piano sheet music for this (If it exists)?

I understand if it doesn't exist. I'm even wondering if it sounds good on the piano...
