Weird font choice. Especially as white on dark background, it's hard to read. The bold is too chunky and again harder to read.
I'm not liking how many scroll down and down websites there are now. I prefer good navigation on the left too.
The header that jumps to reveal summary when you scroll over is irritating because user expects to click into that box and not have a game chasing the url anchor that's trying to dodge their mouse.
