Twenty scenes. Press R to go back, A to go forward. That's the whole interface. And honestly, that's all it needs. The animation itself does the talking, or rather, Elizabeth does. From that Bioshock Infinite parody, you know the one. Brunette, big eyes, and a very specific set of skills she's eager to demonstrate.
The sound design is the real star here. Her voice, the wet noises, the little gasps. It's all mixed really well. The multiple camera angles let you switch from a wide shot to a close-up of her face, which is a nice touch. The POV tag is accurate, you're right there. There's a handjob scene that transitions into a blowjob, and the cumshot is... thorough. The animation is smooth, not that jerky flash stuff you sometimes find.
But here's the thing. The "perfect animation" claim in the description? It's a bit of a stretch. Some of the transitions between scenes are a little abrupt. Like, one moment she's looking up at you, the next the camera has cut to a completely different angle and you have to reorient yourself. It breaks the immersion a little. Also, the zoom feature is cool, but it can get a bit pixelated if you go in too far. I spent way too long trying to find the sweet spot on that zoom, just to see the detail on her lips.
The whole thing is deliberately unpolished in a way that works for it. It's not trying to be a AAA game. It's a quick, interactive animation for a specific purpose. It knows what it is. And what it is, is a pretty decent way to spend a few minutes if you're into this sort of thing. Just you, the screen, and Elizabeth. No combat, no story, just the good stuff. Though I do wish the A button would sometimes just loop the current scene instead of moving on. That's my one real complaint. That and the zoom.
