Not much effort.
I'll give it a 5, don't get me wrong, I absolutely LOVE Silent Hill music, I mean seriously, I listen to that all the time.
But it didn't really take much effort, just imported some songs into flash and scripted some buttons.
So I gave you a two, for effort, and a 3 for the fact that you got some of my favorite songs being in there, my favorite being the main theme.
