I was a bit sad to see that if you get defeated, it gives you the most basic scene ever implying sex but doesn't show it even though it would have been so easy to just do that, for starters.
Losing to anything in the kobold area gives you the exact same scene, even if it's the boss. (This also means any enemy design is just eyecandy. Too bad if you like what you see, you can't do anything with it) Definitely no in-game animations, it looks like it's all CG. Gonna run through with my gear and see if it's one of the games where you have to defeat things to get anything fun, which'll be sad if so but I suppose this is one of the games where it makes sense in context..
... but if you're going to imply sex on game over, then why not just... do both? Oh well. Let's see.
SLIGHT SPOILERS FOR GAME'S LEWD CONTENT BELOW:
EDIT: It's victory sex based. You get a single static defeat CG that isn't animated per ZONE, not enemy or area. This seems to have a tendency to be something lackluster like after-sex oral, or not showing vaginal/anal sex at all. The victory scenes happen after defeating each boss (there are two, both are animated; one for the camp and one for the forest/village) and involve the protag allowing herself to be taken by the boss she defeated while they shower her in typical dominant powerplay dirty talk. Additionally, if you return to the beginning of the game after beating the first boss, you unlock an additional animated scene that's just rimming. If that's your thing, this game will be for you. (if it's ever completed)
Sadly it isn't mine, but hey -- all the power to anyone this helps make a decision.
