I built a tiny one-rule grid puzzle. Rule: your trail is a wall, you cannot cross it. You start bottom-left, the stone is top-right, and 22 steps is the short way.
The problem I cannot shake: the wrong turn is supposed to cost the run, but I counted it and it only costs 2 steps. A careful player can still walk back out. So the trap is soft.
What I want to know: when you hit the dead end in the middle, did it feel like your mistake, or did the map let you off? The end screen prints the exact route you walked. Paste that string here and I will tell you what your walk did.
