@Tig: I found a great map. The name is CHAMPION, it's on:
gamebanana.com/mods/144391
1 opponent, 1vs1: makes super fun !
At LVLWorld CHAMPION is still missing. I do not know myself legally, whether the may be simply copied on LVLWORLD !
The author is: Scorn/or/Unknown (real name : Samuel De Cruz).
Maybe you can get the permission for LVL ?

@BOCKWURST : Adding this one to the map queue for review.

It is a pretty simple map. There are a few like this on already on ..::LvL :)

sweet baby jesus... gamebanana is still a thing!

I would never have known this map was fun if I had never launched it. Good thing I did launch it :P Glad it made its way to ..::LvL, too.
