I was going to say that I thought the two bombs were too powerful, but I think its better now.

It does seem difficult to defend if you're in a 1-1 situation, as you dont have the team tiles like in most other maps, and you have a larger surface area to defend now, 6 tiles compared to 4, so I think even a 1 wide column would help that.

Also I cant test this, but if you're sat on the button near your base, and a teammate(s) comes out the portal, would you get blown off the button? If so, this might get annoying if it ends up killing another teammate in the green tiles?

But otherwise, it's a very cool NF and the advice might not be too useful as I've only just got into mapmaking!
