I was recently watching a compilation video of weird PC games, which included Jinx, a Europe-exclusive platforming title where you play as a jester. This suddenly reminded me of having played a game on Steam, probably 4-5 years ago, where you play as a muscular man (kind of reminiscent of The Tick) in a blue (purple?) jester outfit, including a hooded mask that covers the top half of his face (but, I think, exposing the lantern jaw) with the traditional jester dongles on the top. I think he has a female partner who's dressed in a more sexy costume, but not revealing (I remember, at the time, thinking that I really didn't want to know how much Rule 34 artwork probably existed of her despite me only running into her in a few brief cutscenes). I think I only played less than an hour of gameplay before getting distracted, and due to my membership on a few bundle sites, I have more games than I care to admit in my library, making it hard to search. The gameplay I recall involved some platforming in a medieval village, I think including moving crates into place to get over obstacles, and fighting city guards with a combination of fisticuffs and jester props. I think there was some storyline involving the jester and his companion being rebels against the king, who wanted to outlaw, or regulate, entertainment. I honestly don't remember the details of the magic involved although I think some of it involved the main character being able to poof in and out of places in the cutscenes, and to be able to summon overlarge items out of hammerspace to hit opponents with.
I did a few searches online, but I keep pulling up other jester games, like Once Upon a Jester and Pandemonium. Part of me wants to say that the character identifies as a clown, or that maybe that's the evil king's schtick, but I'm uncertain on that.
