Oh right, I put it there so One could get into the tunnel easier. I guess if I removed/moved it I could get a few extra inclines or maybe two spare blocks?
Yeah, I think tht would work. These are minor things, though - I'm sure you could find a bunch more just by walking through the map.
It looks very good, but in the 4th pic, you used a double wall, and it might just be me, but I think those are the ugliest pieces. they also cause a lot of framerate. If I were you, I'd get rid of it.
Agreed. I've noticed that some of your piece usage was, like what Spincycle said, predictable. In the picture of the red team spawn room, I notice the usage of double walls. You can make it look a lot nicer by exchanging that piece with a different piece. Also, like what Spincycle said, you can exchange many pieces to break up the greyness, make the map more aesthetically pleasing, and, out of all that, retrieve more budget so you can enhance the map's overall gameplay.
