Basically the title. I think that an additional option to field configuration could be a diagonal wall would be great. It would use the same diractions as the curve option but would be a zik zack line of walls.
I'd like to have that option since straight or semi straight walls are more efficient in terms of how many turrets can attack an enemy at a time.
I might consider that, the corners are there to make nice corners, never considered diagonal pieces... I'll implement it when I have the time (currently working on angels mods)
