Nice game! Cool little twist on a known mechanic to fit the theme!
I gotta say, I was done on my first playthrough but then I saw there were ranks… Way to get me hooked! (Couldn’t make it past Diamond though :P)
Fun and simple. My only pet peeve is that the music does get a little repetitive, especially if your run spans several minutes. The tempo changes are a nice addition to mitigate that, but I would have loved at least one more track to cleanse the palate.
Cool entry!
