power up the portal, then jump into it and get teleported to
the next sector. Stay away from acid, it will kill you!
Don't let any monster get near you, their touch is lethal!
Pick up the gun and kill monsters to score points, the more
dangerous a monster is the more points you'll get!
At the end of each sector, you'll be awarded bonus points for
your health, so don't let those pesky monsters harm you!
Try to get out of a sector as quickly as you can, the more air
you save the more points you get!
