Looks pretty Kewl, Would suggest adding more unique obstacles, i've seen a ton of mods like this, what separates a mod maker from another mod maker is their ability to create never before seen environments. Looks good, but sadly I've seen mods like this, next time, work on adding more unique structures or obstacles and truly express your style of modmaking
Just saw the second WIP, took the words right out of my mouth. Good job with the addition of obstacles. Haha
But one thing i see that could be improved, is the random blocks everywhere, when you make a building, vision realism, and what would actually be on a rooftop, add small details that would make those "random" blocks more clear. Not just random stuff thrown out to climb upon.
Good Job on what you did though.
