Editor review
Crypt Knot is a graph-untangling puzzle. Drag nodes to remove edge crossings. Fifty knots across four difficulty bands.
What works is the planarity-test logic. The game validates planar configurations instantly. As someone who works with graphs in security, I find the connection to topology satisfying.
Fifty knots with node-count escalating per band. Late bands include graphs where planarity is achievable but non-obvious.
Tested over weekend cafe sessions in Madurai plus a few Madurai buses commute rides. Touch drag works fine; mouse-drag is equivalent.
Where the design earns its rating is the optional proof-mode. After solving, you can request a formal planarity proof showing why the arrangement works.
Where I would push back is the plain visual style.
Three-and-a-half stars. Solid topology puzzle with respectful proof-mode.
