This is my first map I ever made, hopefully it is not too easy, or too ugly.
From my testing, I would rate it medium difficulty, but I'm also not the best player... :P
I tried to make the Terp more of a necessity rather then a convenience, more-so if you start in the castle.
I also tried to make the map look like a mess, but hopefully I didn't make it too cluttered looking.
And as a final note, I would recommend you rush for the Bertha in the beginning. It will help once you see the middle of the map fill up. ;)
I'll give it a try. Feedback later. :)
Great map ! :)
