Eigenmoon turns linear algebra into puzzles by moonlight

A Hacker News submission by jessicarumbelow links to Eigenmoon, a browser-based puzzle game built around linear algebra concepts, hosted on Vercel. The post drew 6 points and 3 comments within two hours. The linked page itself could not be fetched, so details of the puzzles and mechanics remain unclear from the discussion thread alone.

    It's a great start, but I find it very hard to understand what is happening because I can't control the animation as the "vector space" animates between the stages. The shapes of the gates are also very hard to distinguish (mostly all some form of rectangle) and the click targets aren't very forgiving.

    Outside of the UI/UX issues it's a great idea, and I would probably play all the levels if those were fixed.

    Fun puzzles. I feel like gates are hard to distinguish from one another, except for the rotation and translation ones.

  3. abetusk

    Very pretty but needs some instructions or other affordances. I have no idea what to do.
