Mouse 1 shoots the paintball (I believe this was in the readme)
It is unfortunately not in the readme included with the final submission.
The blog posts were virtually mandatory and it was detailed within my blog post. Including a video.
With 34 final submissions, there are somewhere on the order of 100 blog posts floating around. Reading them all was not an option given various external time pressures, so I endeavoured not to read journals during the judging phase, to avoid conferring an unfair advantage. This was a miss on my part, and a sad side effect of the day job not always staying a day job :/
One of the (relatively few) issues with this year's competition, I think, is that we didn't establish a strong baseline methodology for scoring. My impression is that I may have been scoring the various categories along somewhat different axis than the other judges. In particular, I was endeavouring to judge these from a customer perspective - i.e. someone who has just downloaded your game from a website, and has no real context. From that perspective, a game that doesn't explain it's own mechanics is not a good experience for the player.
