Moonstone Knight
“Make a small platformer: a knight runs and jumps across floating stone platforms to reach a glowing gem.”
Play itMake a game with AI and play it in your browser
Describe the game you want and the Voidless game agent writes the code, in Godot (2D and 3D, with downloads for Windows, Linux and the web) or as a 2D HTML5 game with Phaser. It runs right next to the chat, so you can play it, ask for a change and play again. Every build is saved as a checkpoint, and the agent makes sprites, animations and sound from the same chat.
Made by the game agent
One prompt, one turn, a game you can play
Two small prototype demos made with Godot, each from a single message with no art uploaded: the agent drew the characters, the levels and the effects itself, then played every part of the game to check it worked. A full game is many turns of the same conversation.
The Little Grove
“Make a top-down adventure: a young hero explores a forest clearing, collects coins and avoids wandering slimes.”
Play itHow the agent works
Gather, build, checkpoint
Every request starts from what your game already contains, so a small tweak stays a small change instead of a rewrite. Every change is saved, so you can always go back.
Maps your game and reads only the parts your request touches, so it works from what is there, not a guess.
A coding model writes the change and the game reloads in your browser. You can watch its reasoning while it works.
Every build goes into the version history. Roll back to any point, or export the whole game as one self-contained file.
Under the hood
One conductor, many specialists
You talk to one agent. Behind it, a conductor reads each message and sends it to the specialist for the job: “add a boss”, “what genres are trending?” and “make a jump sound” each go somewhere different.

Built for real projects
Built for a whole project, not one prompt
Your game keeps growing over many sessions. These keep it safe and on track.
Every build is checkpointed automatically. Roll back to any earlier version in one click.
It keeps a design document with your game’s mechanics and your rules (“keep it pixel art”), so it stays on track in long sessions.
Ask what’s trending or how a specific game handles a mechanic. The research agent searches the web and cites its sources.
Download the game as one HTML file with every asset inside. It runs offline and keeps working even if the originals change.
Your generated assets, in the game
Sprites, animations and sound you make on Voidless belong to the same project. Ask for “use my apple sprite for the food” and the agent wires the real asset in. No downloading, re-uploading or copying URLs.
Generate sprites, characters and tilesets, animate them, and use them in the game by name.
Generate the audio in the same project, then ask the agent to play it on the events you choose.
Questions about the AI game agent
Do I need to know how to code?
No. You describe what you want in the chat and the agent writes and changes the code. You play the result in the browser and ask for the next change in plain words.
Can it make 3D games?
Yes. Godot projects do 2D and 3D, and the agent can make .glb 3D models for them. Phaser (HTML5) games are 2D.
What if a change breaks my game?
Every build is saved as a checkpoint. Open the version history and roll back to any earlier version in one click.
Can I take my game out of Voidless?
Yes. A Godot game downloads for Windows, Linux or the web (itch.io or any host); an HTML5 game exports as one self-contained HTML file with every asset inside. Both run offline.
