My Jetpack Levels

As mentioned, Jetpack is an old DOS game by Adept Software that is similar to Lode Runner, but your character has a Jetpack so you can fly around and collect all the emerald gemstones scattered  all around each level. It's a platformer with a twist. You can;t use your Jetpack though unless you have fuel. When you've collected all the emeralds, you have to get to the exit door. Watch out for the eight types of monsters that will annihilate you if they touch you.
