The area is already ingame, but unacessible. I'm somewhat decent in C# (the language the game is coded in) and managed to make the game think I had activated a warp pad in the snow area, so I was able to explore a bit. I have a few more screenshots, but I don't know how much the dev's would let me reveal (I don't even know if they're ok with this one, if you aren't I'll remove it).
The coding for this game is some of the most solid, well organised code I've ever seen, so keep up your solid work guys, and if you aren't ok with me playing around with it, I'll stop. <3
