Two sisters.

So, there's been a long period of inactivity on the forum, and suddenly maps started appearing one after another. I'm currently in the middle of my exam session and will be leaving soon, so I probably won't be able to play them until after I return. I also need to finish some of my own projects, and I don't have any time right now. Based on the screenshots, it looks great; if I find a free hour, I'll let you know.

By the way, the name sounds very familiar, as if I've seen it somewhere before. Or maybe I'm just confusing it with the name "2 brothers").
