I really enjoyed the 2022 one. Some of the smaller indie game alliances turned me on to some really cool games. And some of the artwork was legitimately beautiful. It had great twists, like doubling the canvas.
I was online when they changed it to white pixels only. Watching the board be erased was weirdly emotional. It was cool seeing the community naturally come together to delete it all from the inside out, in the shape of an expanding heart (roughly).
Not saying it’s not a gimmick or anything. Just a cool event that a lot of different communities have fun with
