This game is awesome.
The first secret are the current top three players and can be found by looking behind the dagger and strafing to the right. The middle skull is the highest score, the left skull is the second highest score and the right skull is the third highest score.
The second secret is the Sorath Stone. The letters on the Sorath stone are the developers initials; Matt Bush, Jon M. and Eugene Nesci. It can be found by strafing left and walking towards the end of the platform. Note that you move faster while traveling diagonally as seen in the video.
