As far as I know, this is the closest thing anybody has made to a 2D Minecraft. It's on world, it's on. I will take that simplistic concept and dumb it down even more. Then I shall prevail! Sorry, went a little A.D.D. right there. This game allows you to edit the world as you play, or if you're feeling daring, you can play other people's worlds that are locked for editing. These levels usually consist of you having to jump across a given number of tiny platforms in a row without falling off and getting sent back to the start. Frustrating? Extremely. This is why I usually just stick with the free editing mode of fun-ness.
