First two daysDay one - mostly thinking on the game idea.
Day two - we've decided what the game name will be - Maande, which means "basket" in West Low German (Low Saxon) language. Walker also set up a git repository for the source code. Rest of the day - mostly laziness, but also the core mechanics of the... well, basket. And a cart.
Maybe not much to show, but I think we'll come up with the playable game within the week. I don't expect it to be one of the best, but the whole challenge is more about fun from creating our own game, than competing with others.
