Kong Studio
The modding workbench built into the launcher. You describe what you want in plain words; King Kong 🐒 — Kong Studio's Claude persona — writes it into your own branch of the game, builds it, and test it.
(Content may not be just right on the first try, so be patient and point out what needs to improve!)
Better than a modding API
Most games hand modders a scripting API and a list of what they are allowed to touch. This one hands you the source, a branch of your own, and an AI that already knows the codebase's rules and design docs. Nothing is off limits — a new tower, a new bloon, a new game mode, a rebalance, a joke.
You do not need to read GML. Just say what you want clearly, then play it and say what you want next!
Your own branch, from the first minute
- Open Studio names your branch once, then works in a checkout inside the launcher's own folder. The game's history stays clean; your work is yours.
- Kong reads the project's
agents/notes anddocs/design/before it touches anything — the same memories and conventions the maintainers work under. - Every tool call asks you first. Nothing is edited, run, or committed behind your back.
- Build & play builds your branch's newest commit and runs it with the save you choose.
- Share branch… packages your commits for Duck; Import share… is the receiving side. Get something good in and you land on the credits page.
In the game, not just in the editor
Running your branch under the launcher turns on the game's developer tools, and they talk back to the studio:
- Show Claude this screen (or a region you drag) — send Kong exactly what you are looking at instead of describing it.
- Reload with changes — the game saves its spot, the launcher rebuilds your branch, and you land back where you were.
- Create commit and Flag this version as stable — the same β flag the timeline shows, straight from the game.
What it costs
The launcher is free and the game is free. Kong Studio drives Claude Code, which runs on your own Anthropic subscription — the studio never proxies anything through this site, and no key of yours reaches us. The optional sprite assist bills to your own xAI key.
Start here
- Download the launcher, unzip it somewhere short-ish, run
BloonsLauncher.exe. - Open Accounts and follow the device setup: GameMaker (to build), GitHub (to share), Claude (for Kong).
- Press Open Studio, name your branch, and tell Kong what you want to make.
