Im in no way an expert, but when it comes to programming in Unity Id consider myself just now getting to maybe an advanced level with so much still I want to learn. I could give it a shot, I looked at Knightmare, doesn't look too difficult to program, seems pretty old school, Id have to teach myself a thing or two properly to do it, but I think I can do something like that, if you're willing to work with someone who is still a little green. I dont have any thing posted anywhere yet game wise, just assests Ive made, but I do have a couple projects I could send you to see what Im currently capable of, most of what Ive done so far is 3D, cant imagine switching to 2D is much harder.
