I made a puzzle game called Spaghetti Network!

The goal is to build a graph that computes a given function.

You start with simple problems like A + B, and later get to multiplication, Fibonacci numbers, GCD, popcount, and more.

After solving a problem, you can also try to minimize the number of nodes and compete on the leaderboard.

Thanks to camypaper, DEGwer, hos.lyric, nuip, semiexp, sigma425, snuke, yosupo and Yupiteru for playtesting and feedback.

Feedback and discussion are welcome!
