Hey there extee, I really love your idea with this map! The framework looks fantastic! I am guessing this is even bigger than ctf5, by a decent margin too. If I had to make a suggestion, I would say to get rid of some of the superfluous platforms around the edges to tighten it up a bit and give fewer things for flag carriers to run around. If it is really hard to kill enemy flag carriers on ctf5, I can't even imagine how hard it would be to hunt them down on here. Other than that, I would probably increase the number of hearts/shields. Where they are placed in general is good, there just aren't enough of them. And then finally there need to be a lot more weapons overall. Keep the base exactly as it is, that is perfect!
Of course those are just my opinions. Do whatever you want, it's good work!
