It's not bad for a port, but there are two major things that can be done for a start (if the author is interested, otherwise I might just do it myself if I get big enough of a motivation). 1. The trees aren't double sided therefore the normals are screwed up which results in them looking ugly, you need to literally replace every tree by hand or find a more innovative way (depends on the software you use). Here is a screenshot from the editor (
