Field notes
The controls include undo and both single-part and full-board removal, suggesting players can revise a layout rather than commit to their first routing. The stats panel tracks pass percentage and streaks, while login is described as a way to carry those stats across devices. The extracted page does not reveal how the budget is calculated or what the board looks like.
