Sprite sheets from prompts (Codex skill)
Copilot Skill generates consistent 4-direction sprite sheets better than Leonardo.ai.
AI generation of 2d game assets such as spritesheets
Wraps Grok image-to-video for sprites, but Aseprite and Leonardo already dominate this niche.

I recently started experimenting with creating games using coding agents such as CC and Codex. What I found worked very well is if you take the pre-made assets (sprites, tilemaps, sounds) and then create a spec/harness together with game engine documentation, Codex (or CC) will do a great job in putting it all together - even play-testing the game for you.
Then I thought...why not take it even further? Create game assets as well!
And here my little project was born - "AI Game Studio". Currently it only supports sprite sheet creation, but I will evolve it into a full-fledged game studio.
I don't want to replace game designers - I've been following many for years and the art and craft to what they do is incredible. The idea here is simple - if you are a small indie developer, you could use a tool such as this to rapidly prototype some concepts before deciding on a direction. Or, you can create a basic/skeleton assets and enhance them manually.
The project uses Grok/xAI - simply because I tried over a dozen different models - from WAN to Seedance - local and API based - and Grok Imagine is the only one that was able to produce good quality results, consistently.
I would love for you to try this out, and leave comments and constructive feedback.
The tool is available here: https://github.com/acatovic/ai-game-studio
Video demo is also linked in the repo.

Free, browser-based sprite packer beats paywalled tools like TexturePacker.
The real hook is the style-pack system: each sprite style ships as a ZIP that defines animations, layers and frame sizes so you can swap visual pipelines without hacking the app. Smart layering rules and constrained randomization make it fast to iterate characters, and the export controls (sequencing, layout, per-frame sizing) show the author thought about real game pipelines. It’s not revolutionary — desktop Java + paid style ecosystem limits reach — but it’s a useful, focused tool for pixel-art workflows.
Yet another Sheets-to-API tool in a category SheetDB already owns.
Handles Webflow Reference fields and Markdown conversion better than basic importers.
Glide and Softr already turn spreadsheets into apps with more maturity.
