Don't you dare say that again. Polyworks is like a decendant from heaven from the view of a mapper. Never ever say anything against it or you're getting sliced by my chainsaw.
Really, Polyworks isn't all that difficult. Its controls are different from mapmaker, but hey, it doesn't make those stupid bumping errors. That's one huuuge point. And by the way, it gives you lotsa more options without loosing any of it's handiness.
However I like that funny coloring you did there ^^. But quite the easy map, considering I got trough it without any problems aside the bounciness.
