This game treads (trots??) a fine line between feeling floaty and slippery and being very precise and deliberate. It's admittedly quite frustrating at times, but it never feels impossible. Agreed with some earlier reviews that the loose momentum of the character as she moves really does not feel like it meshes with the strict timing and placement of many of the jumps sometimes, but the addition of a shadow would significantly improve this.
The double jump feels like an easier to execute version of a certain fireball stall technique in Hollow Knight, which is good because I'm garbage at stallball ;) It was a satisfying move to pull off, but I did feel like i struggled to keep it consistent. Eventually i had to put the game down because the combination of the movement tech and the sex minigame buttons (even with skipping, because sometimes i'd press e by mistake or at the wrong time near a mare...) by hands got really worn out.
It's well made and i won't begrudge a difficult platformer at all, and the visuals are clean and nice-looking, very show-adjacent appearance that makes it feel fun and colorful. I think my favorite blend of kink & mechanic was the utilization of cock TF as a sort of consumable item per level; the kink itself isn't my thing but it's such a creative use of the idea and really made me look out for where to "use" her in each level!

I wasn't able to cobble anything together in time for SJX, but I wanted to leave a few reviews anyway, so spoilers for anyone who has not yet played;
