This game has three main puzzles, and is a cinematic game with nice background descriptions.
I struggled a bit with the game, as I didn't speak german. But it is very short, and the medieval background was really fun.
I've provided a small walkthrough:
(Spoiler - click to show)To get over the wall, jump then pull yourself.
For the forest, stick sticks in the ground.
For the man, alternate fighting and talking, with a lot of talking.
