Returning to Pride Month media, I played Mighty Jill Off by Anna Anthropy. If you're looking for a precision platformer made by a trans woman and you've already beaten Celeste, fear not, for this game also exists!

The setup is that Jill has to earn the right to lick her domme's boots by platforming her way up a creepy tower past various obstacles such as fire and spikes and deadly skull-spiders. The kinky content is only in the framing cutscenes, but it does make you spend the entire game thinking about the D/s dynamics between game developers and players, which I believe is the point. You keep hitting the spikes and dying, grr! But you keep trying again and again because you have to prove your worth, or maybe you just crave punishment. When you try to exit the game it asks if you really want to safeword. Good times.
The game is short—I didn't check the time, but I think I spent maybe an hour on it—and the platforming is not actually that hard. (Certainly not as hard as Celeste.) There are a lot of checkpoints. Make sure you note the controls before you start, though: pressing jump again in the air stops the jump early, and hitting the jump key repeatedly makes you slow-fall. You have to spam the key aggressively for long stretches to get through some parts, which can be physically uncomfortable, but again I am sure that's on purpose.
(I guess a lot of people learned of this game because Jill is an unlockable character in Super Meat Boy, which I have never played, but I'm told it's good. It's not currently on my wishlist, but maybe if one of the devs comes out as trans I'll consider it.)
