The character is an OC named Cherry Bubblebelle Delphinium. She's my own take on a Fusion of Princess Bubblegum (from Adventure Time) x Sakura (from Naruto)​

Finn is having the most fanfic-ass day of his life here. The game basically feels like somebody took Adventure Time, binge watched all the Fionna & Cake stuff on HBO Max, got horny, opened Photoshop and Ren’Py and said “yeah ok this is fine” and then somehow it actually kinda works. Plot is simple on paper: Finn ends up in a dimension where everyone is girls, but it plays out more like one of those old AO3 genderbend fics where canon took a vacation. You roam around in a small sandbox map, poke at locations, grind some basic tasks, push dialog trees and slowly unlock scenes. What sold me is how much it leans into Fionna as not just “female Finn swap” but as her own hot mess. She’s drawn with this chunky big tits / big ass combo that would absolutely never pass on Cartoon Network, but she still talks like a discount shonen hero who watched too many anime dubs. One moment she’s teasing Finn, bending forward just a bit too far while pretending it’s all innocent, next moment she’s being a total gremlin about treasure. It feels like reading a horny doujin where the artist actually watched the show instead of just using a wiki.

There’s this early scene where Finn wakes up in the new world and meets Fionna in what’s basically a cheap parody of the treehouse. The background looks like someone used Clip Studio and called it a day, but the characters pop anyway. When she leans in close to “inspect the damage” on him, the camera crops in on her tits in the most shameless way, and he’s trying to keep his hero face while clearly hard. It’s not subtle. At all. But that’s the fun. Dialog tries to mash canon Finn’s awkward boy-scout vibe with hentai-protag energy, and sometimes it clashes, like he sounds too self aware for his own dick. Still, the teasing is actually hot because the game drags it out. You don’t get instant full sex on first visit, you flirt around, run some dumb little fetch errands, get a bit more cleavage, thigh, butt jiggle in each new CG. The humor helps too. There’s a bit where he compares this all-girl world to one of Ice King’s old fanfics and Fionna just deadpans like “who’s Ice King” and it lands harder if you remember the original fake-fanfic framing from the show. Or misremember, whatever. Also, I’m still annoyed the map icon for one area is just slightly off center. Every time I click it on my tablet in Chrome it bugs me and I keep meaning to complain and then I just end up chasing another scene instead.

Visually it’s not “pro studio hentai game” level, but that’s fine. The art has that slightly uneven linework you see in Patreon artist packs: some CGs are polished and clean, others feel like sketches that got colored at the last second, but the bodies are drawn with real obsession. The way they handle big asses in tight shorts, especially on Fionna when she’s half turned toward you, is straight up thirst-driven. The animations (not going into detail, you’ll see) are more like frame swaps than fluid motion, yet they focus exactly where your eyes go anyway. And yeah, it’s a parody so personalities are dialed up in stupid ways. Fionna flips between tsundere, pervy bro, and clumsy heroine, sometimes all in one dialog branch. There’s a sandbox structure, you wander, talk, unlock, repeat. Oddly relaxing, even when you’re just clicking through text and trying not to miss a teasing line about her ass. Some scenes hit like those old Flash games on Newgrounds, others feel like someone’s horny Discord server project that escaped. On phone, I played it in Firefox and the text occasionally wrapped weird around longer profanity, which somehow made the dirty talk feel more raw. It’s rough in spots, sexy in a very “fanfic that went too far” way, and honestly, it feels like the kind of AU where Finn walks into the wrong dimension and the author never intends to send him back.
