Over the January 30th weekend, I participated in the Global Game Jam. On Friday, I drove down to Waikato University in Hamilton. After the keynote from World of Goo creator Kyle Gabler (starts at about the 1:35 mark), we split into groups. A guy named Andy (who has started a game company called GameMold) grabbed me and we went off and came up with a pretty decent concept in about 20 minutes. A few other guys joined us and we brainstormed for another hour or so. Eventually, though, we came back to our original idea and began prototyping it. A couple of the other guys split off and created Wardance, so me and Andy worked by ourselves and created SnowLemmings over the next 48 hours. I wrote the not-entirely-stable code while Andy created all the art, selected the sounds and music and designed the level.
It turned out quite well, and was definitely one of the most polished-looking games at the Jam. We are continuing to work on it, to polish it up and expand the game play after we recover from the lack of sleep and hygiene.
