Tips and Tricks
Word of warning: if warning signs marked with exclamation points appear in the air, it means the immediate area is about to be bombarded with lasers.
To release a constant stream of ammo press and hold down the 'fire' button.
It's vital that you pick up time clocks because if your timer reaches zero, aliens will automatically snatch you up and your game will be over.
The best power up you can find in the game is the jetpack. It allows you to fly around with ease in the stage, shooting enemies that come from above, as well as ones on the ground.
The magnet power up is also useful, as it draws out-of-reach coins closer to you, in case you don't feel like going over and getting them.
