ok, so I took a look at this map...
The Graphics... is nothing... empty walls, but I think U are just testing with this type of gameplay, So I don't even care about how the map looks at the moment, that is future process.
So, the gameplay idea is not new... but I think this is an idea, that can be bothered and it should be.... since I think this one is a good diea, but there have to be some tweaking done.
First of all. the map is too small for 10 players imho... And there are some gameplay problems in the way u placed the goal and the wall behing it.
First of all, there isn't much space for offence if they want to face the Goal. They cant stand infront of the goal (doh... they can, but it is too cloes to the goal, and i u go there, the keep probably kills ya) The Penalty Zone being the wall is way too large. Should be smaller. And the wall begind the goal, should be wider, (conculison: make the map bigger too)
I think u should start a completely new map, with the same idea, and with some tweaking and implents that are mentioned above. I think this idea, is good, and there is still plenty of gold to mine from this idea... Keep Op The good work
