I turned this into a full game with unity cli + opus 5.5, also opus did this full demo video, it played the game with multiple characters and spliced together the best bits, holy shit we're in the AGI era. Play it on your browser here:

This is awesome! Glad we are early to it. Most people have no clue this is even happening! I’ve been working on so many different projects. Most recent one is this pixel game. Almost similar to this!

Woah love the camera + artsyle

Thank you! I was going for this look similar to Octopath on the Nintendo switch! Currently working on a good story mode for it 😄

We are in this weird space where people are building awesome stuff, but there is such a flood of it, it’s hard to get users on any one thing. What are your thoughts on gaining traction with something amongst so much competition for attention?

hmm I agree most people doing these demos whack em on vercel/gh pages and its a sort of ephemeral place where the demos die! if there was some platform with distribution that i could publish this game on I would! Gimme a CLI/MCP and make it one shot opus prompt to add it to the platform and I will :)

It would be rad to port it to a SNES or Sega Genesis cartridge and play it on a physical console. They one shotted the Zelda ocarina of time, mind blowing

That's a great idea, you could port then load it onto the cartridge for the customer and send it to them. Could just be an MCP call

you took the prompt and ran with it! nice work 🫡

Thanks for the original really opened my eyes to what opus can do

It looks cool. I made this game using Qwen 3.8 Flash.

very cool, howd you do the artwork ?

Completely just code

Incredible, any pointers?

Did the model understand the game mechanics or did it just mash keys until the HP bar hit zero? There is a difference between playing and hallucinating victory.

It defeated the boss so it had to understand the mechanics definitely

This is the part that hooks me. Not the one-shot demo, the model playing multiple characters and cutting a reel of the best bits. Feels less like a tool spit out a game and more like a collaborator learning the stage. Sometimes I feel that making the game with a partner is just as fun as playing it.

Exactly it's so impressive it can do this now

You made it into a game! How hard was the steering?

Not very hard it had a few bugs that I iterated on but it figured em out pretty quickly

really cool man good job

Thanks :)

Opus 5.5 on max effort? On my experience opus cant draw good pixel ary on medium. Quality start on high

High effort not even max

opus playing its own game to cut the trailer is genuinely unhinged. did it pick the best bits or did you

It picked the best bits I adjusted the pacing a little with a few more prompts

Damn is this MapleStory?

Heavily inspired from it :)

@rehan_shein Hi! I thought the game you made with Unity CLI + Opus 5.5 was awesome. I was wondering how you generated the art—was it made with AI?

Claude code created the artwork with code

Great results

Thank you :)

this is sweet! would love to see this hosted on @RemixGG_ we actually use @fal in our game generation pipeline in our new desktop app! would love to hear your feedback if you give it a try

@RemixGG_ @fal How do I host it?

the models are magical

also been working on something

gg

awesome to see the progression! any chance you'd open-source it?

how did you make the assets?

Assets all are procedurally generated with Claude code!

we are so early.

I’m really enjoying Opus 5.5 too! I made this pixel art game with it, and it even created the trailer by actually playing the game with the characters and recording it.
