This start of this round will have you falling down a canyon, and you'll have to keep jumping from rock to rock to move up. Throughout this stage you'll encounter ninjas, who'll either stay in place on a rock or will be flying around.

Enemies will become more frequent the longer you survive, so spray shurikens everywhere if necessary. Taking a hit here can lead to an instant death, so it is usually worth it. The rocks will get smaller and some large jumps will be required, so use the somersault jump to get across from platform to platform.

Eventually you will get to the sub-boss of this round. Some feathers will appear on the screen, throw a shuriken at them and the sub-boss will appear. A flying warrior will appear, who is armed with a sword. He'll fly around above you for a few seconds and then quickly move across to the left or right, trying to slice you. Use the platforms on the left or right of the screen and use a somersault jump to leap over him and avoid his attack.

After he's made his move, throw some shuriken at him. After taking a few hits, he'll revert to his feather form, so just keep repeating the process. The only difference will be that the sub-boss will move faster the more damage he takes. Eventually he'll just explode into feathers.

At the start of the next stage, run to the right and you'll see a door. Before entering it, duck and throw a shuriken, and you'll break open a hidden box which contains a ninjitsu item. Walk to the door and hold up to go through it. You will enter a house full of traps, and the first trap you'll come across are sets of spikes which burst out of the floor. There are also ninjas throughout this place, but they are far more aggressive than the ones you've previously encountered. They will run at you and then do a flying dive kick. Try to take them out before they jump.

In the next room, you'll come across a door with several item boxes next to it. Don't go through this door, as it simply leads back to the previous room. Instead, you'll see an item box above you -don't break it open, but use the off-the-wall jump to get on it. The aim here it to keep moving upwards, jumping from box to box, until you get to a door at the top right corner of the screen. Watch out for the flying ninjas in this room, as there are several of them.

In this next room, you'll need to wall jump between several pillars, and carefully time your jumps so you don't touch the spikes, which are placed on the top of each one.

Move to the right, but do not drop down when you see some small platforms and a sorcerer. Instead, kill these enemies (there are a couple of them) and use the platforms to make your way to the right. You will need to wall jump some pillars again, to get to the correct exit of this room.

In the next room, move to the right and kill the ninjas that run towards you. You'll see a door and some spikes. Ignore the door, and instead keep going right. The spikes will keep smashing together, and if you get caught between then, you'll die instantly.

Try and kill any ninjas you see before making any jumps, as their shurikens will knocked you into the small spike beds or, even worse, into the larger spikes. At the end of room is a door, go through it and you'll enter a room with three doors in it. The door to the boss is the larger one with a mask above it. There is also a door you'll have to somersault jump to the right to reach, which leads to a bonus room with several items (and a few bombs) in it. However the exit to this room leads back to the near start of the entire house, so only go in it if you are low on health and/or shurikens.

The boss of the round is the Ninja Master -he's returned, only now there are two of him! They'll keep using the six doors in the room to change location, and when they re-appear, they'll fire some projectiles at you.

The trick here it to throw a shuriken at the head of one of the shadows -only one of these shadows is the true target, as the other will just disappear when hit. You'll know if you hit the correct shadow as it will flash and change to his normal colors for a brief moment.

Once you've hit the boss enough, he'll change tactics. The room will brighten up, and the shadow clone of the boss will be gone. The boss will keep using the six doors to move around, but will now start throwing three fans up into the air. These fans will home in on you, and cannot be destroyed, so run out of their way.

When the boss swirls his hair about, he will release a barrage of shurikens around the room, try ducking in a corner to avoid them. His only other attack involves him using the top three doors. He will appear and run across to the left or right, causing some spikes to pop out of the ground. Some fans will also drop down from above, but these move far more slower than the usual fans.

You can also destroy the dropping fans with shuriken. Keep throwing shuriken at the boss whenever you get the chance and he'll eventually die -hopefully for real this time.
