Ill detail you myself. One is, that a player grabs the blue flag from blue base 1, and a player gets a flag from blue base 2. A player of the opposite team gets a flag from red base 1, but both the blue players go to the other red base and bingo, red team gets 2 points at the same time. How can you play like this, 2vs2 is impossible because in 2 vs 2, one player is usually the defence, and one is the attacker, you basically cant defend, for one base will always be undgarded. There are other bugs, but this one comes to mind first.
I wish you would understand what i am trying to say, but sadly i do not know how to write my feelings about this. Turn back while you still can

Also, about the design of the levels, sure. But I may design in a way you dont want the levels to be like, so you may want to download some of my LATER works (namely my CTF pack) and see how i design CTF levels. But if you dont ccare how the design wil turn out, sure, if i have time ill be glad to design the levels for you, but not entirely, since these are your levels, and you should be the one making them. Otherwise, if i do help, id like to be credited
