I had grand plans for 1st Kajam: https://alakajam.com/post/235/a-la-kajam.
How did it turn out? Well, I managed to get a game out, and there is some polish to it, but nowhere near to what I had in mind.
It seems working on a game for a month or so is much harder than working on a game for just a weekend.
It was a pleasant experience anyhow, so no regrets.
