Find the path to red_ball friend

In this game, you will play as a red ball in the forest to find his missing red_ball friend. Someone saw your missing friend nearby the old castle field yesterday, so you decided to check if your friend is there or not. However, it is not easy to reach the castle: you have to migrate across the old dirt field, and then enter the mystical forest to find the appropriate entry. If you go the wrong way, you might fall down from the edge and die. Let's try if you can find your friend successfully.
