Fun idea for the "mobile home," but could use some balancing tweaks: right now you can pretty much live forever by picking up your tree and walking in circles around the perimeter of the map. Maybe you should get tired from carrying this huge thing for long periods of time?
I really like the idea that you pick up the tree and can never leave its proximity. It was a bit confusing about the area you were transported to, was there a way to get further, or was it only to stay alive as long as possible in that place?
