isn't that one single scene?
Two so far (the eye masturbation one, and the doppelganger)
I know that's not much yet - but because the game's only at v0.6a, and Shine changed its official name from Too Much Light to The Lust Madness, and because she added an entire mechanic and UI elements for it - I'm making the tentative assumption that she intends to make this a reasonably prevalent aspect of the game.
The optimist's assumption would be that this will develop into a mechanic affecting how the MC interacts with her fellow humans, not just the enemies - if she returns to camp with high Lust Madness, she may be more inclined to get on her knees for the shopkeeper, or let Adriano pound her on the couch, etc etc
it's not very prelevant in 3d games that I've seen
Yeah so I think that's what they meant about this game being a great concept. Nothing exactly like it as far as I can recall (I know Yuna is vaguely similar in terms of 3D zombie shooter with seggs, but not sure if there's any lust/consent mechanic?)
