Ramassez les poteaux, puis glissez sur les rails !
Your mission is to reach the finish line.
But you have to pass it from the roof.
You have to pass through each roof until you reach the finish line.
Between the roofs there are only rails.
You can use poles to slide over the rails.
Collection of many poles, so the longer your poles, the safer you slide on the rails.
Reach the finish line safely.
Can you?
