Hey, that was actually really cool. It took a while to figure out what to do, but when I did, it all made sense. I liked the complexity of the tree's life cycle, and how things could be dragged around the scene. It would have been cool if these dragged objects were affected by gravity and physics, but otherwise, awesome stuff.
p.s. I may have overpopulated the planet with trees, it's a bit of a mess on my island.
