TIPS AND TRICKS

* At the start of the game, concentrate on loading as many crystals as you can. Don't worry about the enemy ships yet as they are easy to avoid.

* The mutated aliens with the tails which appear later in the game are worth the most points. You get 1,500 for a direct hit destroying them, but also points for each near non-fatal hit. Get a few hits off-target if you can, as they can be worth 1,300 points each!

* Keep an eye on your shot power remaining and be ready to collect a crystal if necessary to recharge.

* If the shuttle appears on screen level with the bottom block, keep collecting crystals and don't drop any off until the shuttle is clear of the block. You can often lose a life if you are carrying a crystal and can't get to the shuttle before it explodes.
