From the README

A layout planner for Reactor 2: Nuclear Tycoon: paint a board, tell it which buildings you have unlocked, and it works out where to put reactors, generators and coolers to get the most power out of the tiles you have.

It is a browser app — Svelte 5, Vite and PixiJS — with the search running in Web Workers so the board stays interactive while it thinks.

Mirror Expanse, Event Horizon, Entropy Isles and Shadowspire — plus up to five custom boards of your own.

fixed island is the puzzle. You can still clear an obstacle on them, and put it back.
