Introducing puzzles to the game news - Berserker

So I was contemplating how to introduce puzzle system to the game. Main goals were not to be heavy but fun and the main idea were to represent the Viking symbols in a meaningfull manner. So the symbols in the puzzle will be explained in a narrative manner with audio prior to entering puzzle mode. Every puzzle found in the game will follow the story and explain better the player why are they there and why we must solve them to pass to the next area of the game. Hopefully, players will like the idea of learning something new...in case they did not know about them.
