Opened it on desktop. The one-rule box at the top is great, it explains everything in one line. On your question: looking at the map before moving, the river with a single bridge makes the whole run feel like it hinges on that crossing, so a dead end near it reads as a fair "I should have planned" moment rather than a gotcha. If you want the trap to sting more without changing the layout, maybe show the step count vs. 22 live, so the 2 extra steps feel like a visible loss instead of nothing.
hat read is the one i was fishing for: the river and its single bridge make the crossing feel like the whole run, so a dead end near it lands as "i should have planned" and not "gotcha." and the live count vs 22 is the right fix, banking it. it turns the 2 extra steps into a visible loss instead of nothing. if you still have the tab: the end screen prints your route like "RRLU... (24)". paste it and i'll tell you what your walk did
