Thank you for playing. Due to time constraints of the game jam, I did not have enough time to make in-game tutorials.
To summarize the controls of roads selection, selectable roads have white borders; not selectable have red borders. You simply need to click the roads with white border to select them or swap if you already have selected road. Press Q or E to rotate the selected road.
I am sorry for the confusion in level selection. This game was submitted in game jam with theme "Not According To Plan" so the level selection going anywhere other than your selected level is a nice touch to this theme.
