An amazing cup all round. The guy I know as the maker of Funky Fortress and the rest of the original Draft Tracks did not disappoint.
The secret additional map not mentioned on the page as of writing is absolutely fantastic being on a whole other level of fun. It's really tough, but worth giving a go at it. I posted a guide in the discussions tab if anyone wants to try it out by unlocking it.

The one glaring issue though was figuring out how to unlock that track. There was a whole ARG behind it that had to be solved and the puzzle design isn't that great as a game. It's possible that if the participants and I better spent our time those days, the ARG might not have stung so much, but I think better puzzle design would have been better regardless.
The puzzles themselves get a 2/5 for trying and almost giving a fun little hunt, but failed due to the ultimate let downs and over exertion trying to solve it.
