OMG, that was really good! You had nice music, great sound effects, and engaging gameplay. I feel a little cheated that I only got third on the leaderboard because it took me less time to get the diamond... But still the fact that you had a leaderboard, a game loop, and a satisfying ending. Really, really well done!

I liked the music so much I donated a couple bucks to the composer.
I'm really interested in how you made the walker. It was pretty fantastic.
