On June 1st, we brought Joey’s Nightmare II to the MuShanghai AI Indie Game Market.
We thought people would jump into battles, experiment with deckbuilding, and challenge nightmare monsters.
Instead, something unexpected happened.
Almost everyone who stopped by our booth went straight to the Card Workshop.
"Can I really make my own card?”
"Wait, it actually generates it?"
"Can I make a Monkey King card?"
"What if I want to summon 100 turkeys?"
Before long, our booth had turned into a giant wish-fulfillment machine.
In the Joey’s Nightmare II Card Workshop, all you need is a prompt.
For example:
A fire-breathing Monkey King
The system will instantly generate:
🎨 Card Artwork
📝 Card Name & Description
💻 Card Effect Code
And then add the card directly into the game for testing.
Every player can create their own cards, archetypes, and playstyles.
The most interesting thing wasn't what the AI generated.
It was what the players came up with.
Some examples included:
Cards named after themselves
Creatures that don't exist in real life, like Antarctic Bears
Characters from cartoons and movies
Random words that simply sounded powerful
Every player had a completely different idea.
And honestly, sometimes even we had no idea what would appear next.
Many players asked how the card artwork was generated.
The current Card Workshop uses an art model trained and fine-tuned on the existing hand-drawn artwork from Joey’s Nightmare II.
Our goal is to keep generated cards visually consistent with the game's original art style while still allowing players to create something uniquely their own.
If you'd like to create your own cards,
the free demo of Joey’s Nightmare II is available now on Steam.
You're also welcome to join our Discord and share the weirdest, funniest, and most overpowered cards you've created.https://discord.gg/4rk6rG8m7
