My improved V2 clone-based 3D engine. [How do I use it?] Use your left and right arrow keys or A and D to turn the tree around. [Did you use any pen blocks?] This was made with no pen at all. Just clones I used to make it look 3D. [Is it easy to remix and create other stuff with it?] Well, It's fairly easy but the tricky part is to stop other clones clipping through objects.
