A ninja is running through the night, on her way to accomplish all kinds of missions. In each level you get a challenge: the first goal is for example to free at least one prisoner and to get back eighteen gems that were stolen by an enemy samurai clan. When you pick up a blue gem you can become temporarily invisible (for 3 seconds). When you pick up a red gem you can use teleportation. You can do a super jump with an orange gem. Grab bonus items like scrolls and try to reach the exit alive!
Use WASD or the arrow keys to walk and to jump. Press X to become invisible for 3 seconds. Press the spacebar and one of the arrow keys to get teleported in the direction of your choice. If you want to free a prisoner you have to type a combination of the letters W, A, S and/or D.
