Seen one, seen 'em all.
First of all, I love the madness series, but I think it's overstayed its welcome at this point. At this point, you're not trying anything new, there is no gap in difficulty from one goon to another (even if the goons have different costumes and are SUPPOSED to be better by implication). It's not even mindless fun, as you've done better work than this. Innovate a little, that's all I'm asking, because it's starting to get stale.
