Prior to playing this game, I had seen it off and on for years on YouTube. It took a while, but I finally got around to playing it.
There's not much to a story to this one. Some aliens are trying to take over the world, and some guy with blue hair who can transform Super Sentai-style is the world's only hope.
Level 1
Left and Right let you move around, Down lets you duck, Button 2 attacks and Button 1 jumps.
There will be robots that fly around from right to left; you'll need to attack them in order to get the power-up inside. The first power-up you'll find - a red circle-shaped jewel - will let you transform from your human form and give you more moves. As an armored hero, you can use weapons and also hold Button 2 to perform a charge attack than can only be charged up and launched while standing perfectly still.
At the bottom of the screen is your score, your health and your charge meter from top to bottom on the left side of the status bar. At the right side of the status bar, you have your time remaining as well as red jewels. When you collect more than one power-up crystal, you'll get gold armor as well as a weapon. When these jewels are lit up, you will lose these instead of health whenever you take damage. Once you lose all the jewels, you'll lose your gold armor as well as your weapon.
The red power-up jewel will give you a sword, while the blue power-up jewel will turn your suit blue and give you a gun, complete with a more powerful charge shot. Just remember that you can have only one bullet on the screen at any given time.
Never stay still; always keep moving. Otherwise, flying enemies will show up and dive towards you to destroy you.
The enemies are pretty easy for the most part. The guys in the green armor mostly advance towards you, while the guys in the blue armor will shoot bullets at you that you can duck under. The flying guys will fly forward, but some of them will dive towards you, so keep an eye on them. If any flying guys are wearing blue, they will drop bombs. You'll want to stay away from the bombs as well as their explosions.
The red, blue and green hexagon-shaped gems just give you bonus points. Hearts refill some of your health. Believe it or not, getting power-up crystals also refills a little bit of health. The square with the gold edges and the "T" in the center gives you extra time. The tube with the heart in it increases your maximum health.
In just about every level, there is one of the two main henchmen on a platform who will fly in, sic alien flies at you, and then leave. You can duck under them all in this level.
The rolling brown guys can be attacked with duck punches or attacks if they're close enough, although you can stay on the higher road to avoid most of them here.
The boss is a frog man. He will jump from one side of the screen to the center to the other side. Whenever he stops, you want to get close to him (but not too close) and crouch punch him to do damage to him and avoid his fire breath. Whatever you do, do not let him touch you. If you have the gun, he's even easier to defeat.
When you do enough damage to a boss, the music changes to even more victorious music. Keep fighting the boss, and eventually the boss will go down. You'll get bonus points based on how much time and health you have left.
You have only one life, and if you lose it, it's game over and it's back to the start.
Level 2
As you fight the brown rolling guys, you'll get a chance to get the green power-up crystal. This turns your suit green and gives you the boomerang, but you have to charge the attack up to get any real distance with it. As a result, I usually avoid getting it.
The tops of the trucks will protect you from the bombs from the blue flying guys, but you'll also have to deal with the brown rolling guys. Pick your poison.
The crawling guys that look like mantises will jump down from the top of the screen and also show up from the sides of the screen. They will move towards you, and occasionally stop. Let them come to you and keep duck punching until they run into your attack and die. Sadly, you have to stand back up to change direction before crouching again, which can make fighting these guys on both sides a little harder than it should be.
The blue guys with the guns now have mortar shots. Not only do the shots hurt you, but so do the explosions.
The boss here is some sort of squid man. After flying around, he will eventually land on the right side of the screen. Whether you have a weapon or not, have a charged attack ready to do some more damage before he attacks. He will attack you with his arms, but you can duck under that. He can jump at you, too, and it's hard to avoid since you have to be close to him to have that attack happen. From here, be ready to jump over the guy when he flies up into the air and then flies around the room. Keep a close eye on him, as it especially helps when he comes out from the upper-left and dives down at you on the way to the right.
