Nah, you shouldn't. Trust me, the people knows where the stuff come from and who made it first. If a shameless copycat troll like this brings out a subpar mod with zero quality and with obvious thefts from other mods including enemy placement and stuff, well, it simply will be heavily criticized, getting negative feedback and pretty much outcasted from the community.
He robbed me my stage 2 of H.U.N.T.E.R. but rest assured that that forced me to pull out a much better stage two with lot more quality than the one shown in the demo. In the end, we know where the true quality comes from.
