Is Slopverse just an AI chatbot with a fantasy prompt?

No. Slopverse keeps event-sourced canonical state. The AI writes prose about things that have already been committed to the world state; it cannot invent items into your inventory, move geography, rewrite relationships or declare that you won. Prose describes the world, it does not change it.

Was Slopverse vibecoded?

Yes. It also has a test suite, event sourcing, invariant validation and exact turn rewind, so it is at least well-behaved. Please do not be mean about it.

When does Slopverse come out?

Soon, in the specific sense of the word 'soon' used by one person building a game on nights and weekends. This page exists so you can find it when it does.

How much does Slopverse cost?

Pricing is not decided yet. Generating a painting every time you open a door is not free, so there will be some kind of free tier and some kind of paid tier, and the free tier will be a real game rather than a demo that stops.

Slopverse — the AI RPG that paints the world as you walk into it

Q: What is Slopverse?

Slopverse is an AI-native role-playing game. Instead of shipping a finished map, it compiles the world as you reach the edge of it: a rumored place becomes a real location with its own characters, props and exits the first time you walk toward it, and a model paints that exact scene for you to click on.

What is Slopverse

It's a point-and-click adventure where nobody drew the rooms first.

This is like so cool trust me. You name any sort of world imaginable and it just makes it. Fully interactive, consistent, just awesoem bro. My brother was "Charliel Kirk" and threw coffee at this one poor guy over and over again. So I mean, it can really do anyting

01

The painting is the game

Every scene is a generated illustration with invisible hotspots sitting over the actual people, doors, clues and objects inside the picture. (This part was actually my own idea like 6 months ago so go humanity!)

02

Or just say what you want

There's a box that says "What do you attempt?" and it means it. Like ask me "Can I do X?" and well actually don't ask me, cuz you know the answer.

03

The AI can't cheat for you

The world is event-sourced. The model narrates things that already happened. It can't hallucinate a sword into your bag, move a mountain, or decide you won the fight. I rebuke u hallucinations

04

Bro the sounds are sooo cool

Man where do i start. Generated 2000 sound effects to pick from just for this. Voices ofc are chosen based on character and are consistent. I mean bro there's a sound effect for a deep voiced male who is drunk laughing. Ambient sounds too. Music!

05

Undo the universe

Exact turn rewind, named story moments, and branching child timelines. Don't abuse it tho guys, be brave.

06

People do things without you

NPCs have their own motivations that update whether or not you're watching, hold private knowledge they don't automatically leak to you, and will absolutely wander off mid-conversation to go do something else.

Actual output

Real scenes!!!

A cartoon-style elderly man in robes standing beside an open manhole in a neon-lit alley. — **Old Tung** So like this guy is one of the Tung species or smth and he really hates the skibidis so he goes down the sewer to kill them. I went with him and tried to walk past a skibidi but i died it was horrible.

A generated bathroom with a bathtub, sink and a window looking out over a city at dusk. — **I Used The Restroom** It was actually a pretty nice experience

A loot card showing a neatly folded stack of blankets rendered like a legendary item. — **Blankets** My game has blankets, sometimes

A chalkboard covered in nonsensical numbers, hanging outside a barn by the sea in the rain. — **Math?** Nope, not really

A man standing behind a folding table on a campus lawn with a sign reading DISAGREE? GET IN LINE. — **"DISAGREE? GET IN LINE."** Alr come down bro.

A rainbow-haired mechanic kneeling beside a futuristic bike inside a ship cabin, in a bright cel-shaded style. — **Um.**I think there's like a hand that's morphing into a speeder bike of some kind.

An illustrated top-down fantasy map of a coastal stronghold at night with long banquet tables and lit windows. — **The world map.** I mean it doesn't look real but like, it's pretty nice.

A robed figure with a sword standing beside a battered propeller plane in a desert sandstorm. — **Any Genre.** Yup you can be in the dessert and get on a plane. Tried it.

A man in a long coat beside brass instruments in a stone observatory, overlooking hills lit with distant lights at night. — **It can actaully be good tbh.** Sometimes it works realy well. Look at this guy!

Full disclosure

Yes, it was vibecoded.
But don't be mean :(

Hi guys. I've spent $400 in codex and claude code credits building this, not to mention the api bills. So don't be ungrateful. I'm a fair master.

It does hold itself together, though. There's a real test suite. The world state is event-sourced with invariant validation, so a failed generation leaves your campaign untouched instead of corrupting it. There's idempotent request handling, atomic model retries, and exact turn rewind. It is better engineered than it has any right to be.

Written mostly by a robot
Debugged mostly by a guy
Both parties are tired

Jonathan, the developer of Slopverse, photographed from below under an office ceiling light. — **Hello.** Proud CS Major at UCI, might go for a PHD in vibecoding.

Say hi to tung, isn't he so cute ⊙▂⊙

Questions

Things people are going to ask

What is Slopverse?

Slopverse is an AI-native RPG. Instead of shipping a finished map, it compiles the world as you reach the edge of it. A rumored place becomes a real location — with its own cast, props and exits — the first time you walk toward it, and the engine paints that exact scene for you to click around in. Then it stays. It's yours now.

Is this just a chatbot with a fantasy system prompt?

No, and this is the part I'm genuinely proud of. Slopverse keeps event-sourced canonical state. The model writes prose about things that have already been committed to that state. It cannot invent an item into your inventory, quietly relocate a city, rewrite who trusts you, or narrate that you won a fight you didn't win. Prose describes the world. It does not get to edit it.

Was it really vibecoded?

Enthusiastically, and without shame. See the whole section about it above, which includes a photograph of my face as penance. It does have tests, though. And invariant validation. And rewind. Please be normal about it.

When does it come out?

Soon — in the specific and legally non-binding sense of "soon" used by one person building a game outside of work hours. This page exists so that when it does happen, you can find it. That's the entire job of this page.

What will it cost?

Undecided. Painting a fresh illustration every time you open a door is not free, so realistically there's a free tier and a paid tier. The plan is for the free tier to be an actual game you can finish things in, rather than a demo that stops in the middle and asks for your card.

Will the art always look like that?

Mostly it looks like the good ones. Sometimes it looks like the prophet standing next to the manhole. You get both.

Can I play it right now?

Not yet. This is a placeholder page with delusions of grandeur. Email me and I'll tell you when that changes.

It isn't out yet.

But like soon guys, be patient I've gotten a lot of requests asking to pay me $1 million and it's a bit overwhelming right now.
