hi, we played your map EpicMaul yesterday and I have some suggestions for you which you should implement.
very fast mode (when creeps spawn there is a 20 seconds timer. when it expires the next group spawns, when the previous wave isn't finished, if every creep is dead let the next group spawn)
one of the players left the game, the problem was that his towers where still ingame and attacked someone elses creeps. Just remove the towers of leaving players
some people were upset that some towers have the same endversion
one of the players was big in abusing. He closed his entrance and the creeps ran to the upper lanes, where they were send back. So he was able to win the game with only four or five maze towers.
it would be nice to change the difficult level afterwards.
edit: and it would be nice if one could choose the start area ingame
