The first thing that hits you is how deliberately rough it looks. Not in a charming retro way, more like someone drew it on a napkin and scanned it in. And somehow that makes the whole thing dirtier. The monster girls in Crimson Keep 3 have these weird proportions, all hips and tits and weirdly jointed legs, and the janky linework actually makes the sex scenes feel more... intimate? Like finding a really explicit sketch in someone's notebook. The devil girl's tail wraps around your viewpoint character during one scene and the animation is basically three frames but it works.

I spent way too long in the first demon encounter. You get this choice between resisting her magic or giving in, and the resist path leads to this surprisingly tense turn based fight where she keeps throwing status effects that make the screen go wobbly. Lost on purpose twice just to see the creampie scene from different angles. The POV stuff is inconsistent though, sometimes you're looking through the protagonist's eyes and other times the camera just floats there like a security feed. Minor thing but it bugged me.

The RPG elements are actually more involved than they need to be. There's a whole skill tree and equipment system that I mostly ignored because I was trying to get to the next monster girl encounter. The furry tag applies to a fox spirit character who shows up around the midpoint and her dialogue is surprisingly sweet for a game where you can finish inside her like three different ways. Multiple romance paths branch off pretty early but the game doesn't really signpost which choices lock you out of which scenes. Had to replay the Lumen City section twice because I accidentally friendzoned the demoness by picking what I thought was a flirty option. The adventure tag is doing some heavy lifting here, it's mostly corridors and dialogue trees, but the magic system has this neat corruption mechanic where using certain spells changes how NPCs react to you. Wish they'd done more with that instead of the crafting system nobody asked for.
