I started late, because I didn’t have a good idea, and I finished early, because I had to do some other things, but for the first time I did my game for the Ludum Dare. It only fits the theme if you misspell it, and it’s even more minimalistic than I wanted — barely a game, to be honest, but it’s done. You can get it at https://bitbucket.org/thesheep/tinworld
The idea is that you are the last human on a world invaded by killer robots — the Tin World. Just shoot as many robots as you can before they get you. Move with arrows, shoot with space.
