Welcome to Space Invaders!

This application has been designed as an experiment to test whether people (i.e. you) are able to overcome challenging situations (i.e. advancing alien hoardes) without making errors.

Can you complete the game error-free?

Can you become the grand master?

Instructions
	Move your ship left and right using the arrow keys
	Fire your main gun using the space bar to kill aliens
	Catch any astronauts falling from the sky, your ship will automatically bring out its catcher attachment.
	If they are moving too fast, keep tapping T to slow them down.
Press R to release the captive:
	Release astronauts over the yellow and black base
	Release aliens over the red and black prison
Once you have released the astronaut, your ship will try to return to its normal state. After a couple of seconds, it will switch to look like the image on the right. When it is in this state, press G to switch back to gun mode.
You cannot fire your weapon whilst in this mode. Attempting to fire will damage your weapon mechanism for a few seconds and cost you a few points! Remember to switch (press G) before firing!!!
