The file contains a folder with 70 music files that make the gameplay more interesting, the two map files and a README.txt file with all the instructions.
It's a 2-part map (actually 2 maps) where you have to defend your castle and - in the second part - venture through the enemy's kingdom with nothing but your king and the 6 knights of the Round Table. You may only use each knight's ability once, so use them wisely! Can you solve the riddle and complete the mission? The first map is more conventional and the second map is in my opinion very unique and interesting.
