Author here — I built this app with Svelte.

Its simplicity and the straightforward reactivity model fit the kind of UI updates this game needs.

Interestingly, one of the beta users already derived a closed-form solution for the puzzle (I still don’t know the details myself).

Because the game only shows Euclidean distances rounded to two decimals, very large coordinate ranges (e.g., 3‑digit values) introduce enough rounding error that an exact solution becomes impossible in some cases.
