After using the convertor, ajust carefully 2-D barriers in cfedit and then try the comp to see if it is good.
Then, it will be perfect (at less for me :-).
I didn't understand those huge 2d barriers. You'll fix it next time. Thought they stopped me from punching (but I was at the wrong control). I also didn't like the marshes. I thought sand would be slower than this...? Anyway, the map wasn't too bad ;)
