Which AC version: 1.0.4: don't make any gema on 1.1
Big/small? big is better: i like maps that take 5~10min to finish it
Hard/Easy? hard
Should it include water? water is very annoying since it can cause lag
Should it have nade jumps? I have no problem with nade jump, do what you want.
I tried the map you uploaded: gasline.
What is the use of this map? is it a beta?
