Before the brave samurai is a serious task - to find five crystals of different colors: red, yellow, green, blue and purple. They are guarded by giants of the corresponding color. To cope with monsters, you need your skill and dexterity in the game Spectral Samurai. The enemy running towards the character has an arrow above his head. If you on time press on the same one on your keyboard when the monster approaches, the hero will destroy it with a single blow of the sword. As you release the stones, with the arrow you need to press the letter that matches the color of the opponent.
