We are accustomed to instant communication, thanks to various instant messengers installed in our phones and smartphones, tablets and laptops. But this was not always the case, and the current amenities appeared relatively recently. It was quite different in the Middle Ages. To deliver a secret message, carrier pigeons were used, but this is not always reliable and the bird will not convey a large package, so a reliable person was most often sent. In the game Castle Shadow you will meet the knight Daniel and his sisters: Michelle and Donna. All three need to get to the royal castle to deliver an important message for the king. The heroes have been driving for the whole day and want to rest. Leaving the forest, they suddenly saw a huge dark castle, it towered over them like an ominous shadow. The view is threatening, but what to do when there is no other accommodation for the night. You will have to visit this gloomy building, and what awaits weary travelers there, you will find out in Castle Shadow.
