Quick answers
What tools do you need?
ChatGPT (ai assistant for ideas, scripts and planning); Midjourney (ai image generation with a strong art style).
How much does it cost?
You can start for $0: ChatGPT has a free plan. Midjourney is paid or trial-based. Check each tool's site for current prices.
Is it allowed?
X allows original content; deceptive synthetic media likely to cause harm can be labeled or removed, and paid posts must be disclosed. Source.
Watch out: Reach, not income. Gameplay that copies a famous game can raise IP questions, so make the theme your own.
Try it yourself
(Our template, not the creator's prompt.) Write a simple physics game in one HTML file with Matter.js: the player drags and launches [character] at towers made of [blocks]. Include a score, 3 levels and a restart button. Then give me 5 image prompts for the sprites and background in one consistent style.
Starter tools
Your first step
Open ChatGPT, paste the prompt above and swap the [brackets] for your own niche.
Full write-up & sources
More detail: He says GPT-4 wrote all of the code and the graphics came from Midjourney and DALL·E 3, and he shared his prompts and process in the thread.
Results: No earnings are shared; this is reach.
Worth knowing: The game itself was a weekend project.
