Walking
	Pretty simple. Push the left arrow to walk left and the right arrow to walk right. You can change these keys though.
Jumping
	Pushing the up arrow key jumps. While in the air you control your character by using the walking keys. Read on to find out how to do a special jump.
The Wall Jump
The Wall Jump is a special jump which allows you to jump nearly as high as the screen and as far as it. Go to one of the corners. The instructions show the left corner. Now start pushing against it. Stay there for a second. Now for the beginning of the jump. Push the jump key (the up arrow by default) and the walk key in the direction you are facing. Keep holding this until you have reached the desired height. If you go too high, you'll start to lose momentum and begin to fall. Now push the opposite way and the jump key. Hold this until you have reached the desired landing spot. Fall the rest of the way down and you are done. Though the wall jump is versatile, it is sometimes difficult to use, and don't forget that you are fighting against gravity.

Killing guys!
First we'll go over the basic bomb attack. Just push the fire key( space by default ). The bombs are thrown randomly, so firing more increases the chances of hitting someone. If you are jumping and you fire bombs then the bombs will go out in a circle. It follows the below pattern, but remember that your aim isn't great so the more bombs the merrier. If you get a weapon in a crate, then push space to use it, usually. To find out more about weapons, click here.
Life
This is your life. Watch it carefully. Each full heart represents 10 life, each half-heart is 5 life, and each little heart is 0 life. So above is 100 life. These are the amount of lives you have. You go down to zero and game over. If an angel flies out of you, then you have lost a life.
Advancing
These are your points. When you get a 1000 points, you get to go to the next wave. To get points, you collect bonuses and kill guys.
