In addition to the awesome song, this was a great game! I loved the controls!
The only problem, was that the bosses could be a tad tougher!
Other than that, a lot of people have been asking about the "Hasn't your Mother ever told you not to look there" or whatever Medal.
To do it, go to the sniper level, and move your cursor to the top left. Then scope in on the middle of the sun. You will become blinded for a second.
The medal is yours!
