A while back I worked on making a dynamic node system; like the static one you see in this game, only movable. It used canvas tags (pretty state-of-the-art). I have it lying around somewhere. I wonder if I could make a clone (with attribution?).
Anyway. I've managed to get to six of the theme nodes. And I noticed you can merge games from the save screen. Anyone want to help out? Post your games in the comments.
