level15

Levels 1 - 5

As in all levels, remember to destroy as much as you can. Just about the only thing you can't make points off of are spikes, so break every crate, set off every arrow and dynomite, and break through wooden floor boards.
There is a map provided for you to glance at to get an idea of what you're about to face. You are the green figure, and your goal is the gray figure. In most of the levels, I have provided you with a picture showing you the area in which to enter the secret areas and to reach the crystal (or an extra life.) Soon, I will add a more detailed way to get through each level.

Level One

Level Two

When coming back out of the secret level, don't jump back into the water. Instead, walk and press up. This way you don't jump onto the spikes, you will shoot straight up to the surface.
There is an extra life in this level. To easily get it, clear all of the treasure and crates in one breath. Grab some more air and head back down to get it. Clearing all of the crates first will save you time later.

Level Three

The quickest way I have found to complete this level is to get the crystal first thing. Do this by climbing up the ladder, getting the treasure off to the right first. Continue climbing up the second ladder and activate the arrows. Wait for the boulders and treasure to fall. Knock the boulder over to the left one to break the spikes. Fall into the secret area hole (shown.) Get the crystal. To get out, walk back to under the place where you first started and jump up. Swim to the top to get air and start moving to the right and crawling down the winding path. Get the treasure at the bottom. By this time the water should be filling in here. Stay in the middle and jump up to hit the arrow. If you just move over to the right or left one space all the way you shouldn't get hit by the four falling boulders. If need be, get some air from the pocket. Follow the channel where the boulders came from up, letting the water carry you. Climb the ladder, head left collecting the treasure and you should be done.

Level Four

This level is really easy. Timing will help, however, since there is an annoying monkey to deal with. Go left, but wait for the monkey to walk towards you and then walk away. Once it walks away, jump up and follow it. Only jump over it when it turns back around towards you. Jump over the opening and hit the arrows. Once the boulders fall, walk off right, but only go straight down. Stand on the fallin boulder and walk into the arrow. Once you do this stay underwater and swim right. Jump out. If you timed this correctly, the monkey should be trapped between the wall and the boulder just left of you. If you missed the timing thing, don't worry about it. It's not all that important. The point was just the get the monkey out of your way. Now, you'll need to move the boulder left one spot to be just under the arrow. Becareful when moving this. You can not kill the monkey, so don't try to roll it over. It will go through the boulder and kill you instead. Not good. So now that the boulder is moved, jump on it and hint the arrow. Move to the right. 9 metal crates will fall. Jump on them and get the treasure, but don't leave yet!! The need to get the crystal. Go back to the left, over the monkey and over the water. As shown, jump up the wall onto the platform. You'll see the crystal easily here. Fall into the water and swim under the monkey (this is just to avoid him) and now you can leave.

Level Five

This level is a level in which water will flow in immediately. You need to move as fast as you can. Jump up as fast as you can to the top. Ignore the extra life for the moment. You can collecet it later. At the very top is a boulder. You need to roll this boulder off the edge, pushing it towards the right, letting it fall onto the wooden floors. Here's something I think will help you a lot, to try to follow along. Standing just right of the boulder, look down. You'll see a bad guy. Once that bad guy is under the path of the boulder, push it left and FOLLOW THE BOULDER DOWN. If you time this correctly, you should miss all of the bad guys. Once your boulder lands next to the monkey, move if off the cliff again, pushing it right. This will knock the boulder into the rising water and breaking the wooden floors, giving you access to the treasure. Once you have collected it, swim to the top. Once on a platform, continue climbing. After you have climbed the ladder, get on the platform just above it and walk off, moving right. Once you land on the extra life, you will bounce off of it. Move slightly to the left, but not all the way. You should land on the platform just below you. Now, continue climbing upwards and out of the level!
I have yet to find how to get to the crystal in this level. If you do know the way, please contact me.

Thanks to Jessie R for the following tip:
"for level five u have to wait for the water to get pretty high (a little above the spikes where the extra life is.) the "secret entrance" is right there, about two or three spots above the spikes on the right wall. fall all the way to the bottom, then run across to the left and jump up the two wooden platforms. be careful not to hit the one set of spikes coming down by heading to the right after the second jump. then just hurry to get to the top to breathe WITHOUT hitting any of the animals... the monkey is easy to avoid but the bird is a little harder. then complete the level like normal."
Coming soon, I will have a picture that will show this.
