Vibe coding a game? Here is how to keep your work safe.
You describe, the AI builds, the game grows fast. Then one afternoon the AI “fixes” something and the game stops working, and you cannot tell what it changed. This page is the short version of how to never be in that spot.
What “vibe coding” a game means here
Vibe coding is building software by telling an AI assistant what you want in plain words and letting it write the code. People do it with ChatGPT, Claude, Cursor, Copilot, Windsurf and many AI game builders, inside engines like Unity, Godot, Unreal Engine, GameMaker, Defold and RPG Maker. It works, and it is fun. It also has one habit that bites: the AI changes files you did not ask it to touch.
The three ways vibe-coded games lose work
- The quiet rewrite. You ask for a small fix. The AI rewrites five other files “while it was there”. Something that worked yesterday is gone, and the AI reports success.
- The forgotten decision. Three sessions ago you decided the player should never lose their inventory. The next session’s AI never knew that, and undoes it.
- The missing copy. You meant to copy the project folder before the big change. You did not. Now the only version is the broken one.
The one habit that prevents all three
Before every big AI change, make a checked copy of the whole project in a separate folder, and write down the decisions the AI must respect. After the change, compare what the AI says it did with what actually changed on disk. If the game is worse, get the earlier copy back into a new folder and carry on from there.
You can do that by hand with folder copies and a notes file. It works until the day you forget, or copy the wrong folder, or cannot tell which of your twelve copies is the good one. That is the day people go looking for a tool.
How Fate Tracker Build Memory does it for you
- One button makes a checked copy. Press “Protect My Game”. Every file is copied into a separate folder you choose and checked with a fingerprint. Unchanged files are stored once, so later copies are small.
- Your decisions travel with the AI. Approved decisions and lessons are written into the instructions Fate Tracker prepares for your assistant, so the next session knows the rules.
- Claims are checked against reality. What the AI says it changed is kept as a claim. Fate Tracker’s own comparison shows what really changed, including files the AI never mentioned.
- Getting work back never overwrites anything. An earlier copy is rebuilt into a new, empty folder, every file checked. Your current game stays exactly as it is until you decide.
- Everything stays on your computer. No account, no cloud, no uploads, no AI subscription needed. It works beside whatever assistant you already use.
Quick answers
Does it work with Cursor, Claude Code or ChatGPT?
Yes. Fate Tracker prepares instructions you paste into any AI chat. Assistants that support local connectors can also read your project status and rules directly, but cannot change or delete anything.
Which engines?
Unity, Godot, Unreal Engine, GameMaker, Defold and RPG Maker are recognized automatically. Anything else that lives as files in a folder works in the “Other engine” mode.
My game is made on an AI website. Can I protect it?
Only once the whole project is downloaded to your computer as a folder. Export it first; a project that only lives on a website is not on your computer yet.
What does it cost?
$49, paid once, for one person on up to two personal Windows 11 computers, with a full refund for any reason within 14 days.
Does it replace backups?
No. It protects the game projects you connect. Keep a whole-computer backup too; a failed drive is outside what any project tool can fix.
