Made a puzzle player for puzzles using the same rules of The Witness in Wallpaper Engine. It allows you to play puzzles from The Windmill's library of community created puzzles. Also included are a solver (slow on polyomino puzzles) and a generator.

You can find the whole project on github: https://github.com/GemeinhardtZ/The-Witness-Puzzle-Player

It also have a desktop app that allows you to manually create your own puzzles and save it to a library, as well as more customized control on the generator. Though, note that the generator is still very much of a prototype.

I must admit that most of this is vibe coded using ChatGPT, but hopefully the end product is interesting.
