Building Asset Forge, my own game-asset studio

How I built a tool for making the art, sprites, tiles and sound for my game, written up one part at a time: what worked, what it cost and what broke.

The series, in reading order

Part 01

Why I built my own asset studio

On 2 October I started a Godot game, wrote down the 97 pieces of art it needed, and paused it the same afternoon to build a tool for making them. Ten days and 66 versions later, the game is still paused.

Building with a team of AI agents

I write cards and Claude agents do the work, one card per run, each in its own git worktree, with a single merge script as the only way into main. Over 131 cards and 274 runs, more than half the cards needed a second run.

Part 05

Making merges faster

Every merge ran every UI check, so a card that changed one screen still waited about an hour. Picking only the checks a change can affect fixed that for small cards. Most cards still touch shared files, and moving tests to my second PC freed a lock more than it saved time.
