Nice! I had lots of fun killing my kids XD The atmosphere is pretty good, I'd say. I can see other human trees in the background. If you were to expand upon this, maybe there could be different kinds of kids to raise and kill, haha.
And now I have a question: are we some spider-tree-man thing? 'Cause to me, it seems we have branches like a tree, a human body, and a weird body with legs underneath the ground.
