I keep thinking about that one scene in Monster Girl Quest where you're just walking and then bam, slime girl. But this thing, this koikatsu fever dream, it's like someone took that moment and stretched it into a whole sandbox where the catgirl doesn't just appear, she's there with a robot buddy and a childhood friend who apparently wants to wrestle you into submission. The tanlines on that friend, by the way, are a specific kind of madness. You wake up, and the game doesn't really care why. It just throws a harem at you and says figure it out.
The domination stuff gets weird fast. You've got your standard groping and handjobs, sure, but then the lactation kicks in during a spanking scene and you realize the pregnancy mechanic isn't just for show. I had a monster girl get knocked up and the pregnant sex animation was so janky it looped through a wall. The horror tag is there for a reason, I guess. The sci-fi elements are just... there. The robot friend mentions something about superpowers, you nod along, and then you're back to deciding if the elf gets the anal or vaginal creampie this time. The voyeurism angle is baked into the exhibitionism, where you can just leave your slave on display in the town square and the NPCs don't even blink. Ahegao faces pop up during the most mundane titfucks.
The hymen breaker tag is not a joke. There's a specific virginity system and the game tracks it with a little blood splatter effect that looks like it was drawn in MS Paint. The lesbian and lez domination content is surprisingly fleshed out, maybe more than the male protagonist's own scenes, which feels like a deliberate choice. The group sex gets so crowded the 3DCG models start clipping into each other, a mess of big tits and squirt effects. I forgot to mention the cosplay. The catgirl has a maid outfit. Of course she does. The orgasm denial mechanic is tied to a BDSM trust system that I broke within ten minutes by just spamming the spank button. It's a sandbox, so nothing matters, and that's the best part.
