Jetpack

You are a daring adventurer in search of precious emerald gems!
With your trusty jetpack strapped to your back, enter and explore
a hundred levels full of treasures and peril. Your quest is to
take all of the gems in each level without getting killed. When
you collect all the gems for each level, the portal to the next
level will open. Collect treasure on the way to earn extra lives.

The jetpack model L1069-E is specially designed for human flight
with great power, but unfortunately it consumes a large quantity of
fuel. You must find fuel for your jetpack before you can fly
around the dungeons. Press down while flying to maintain constant
altitude. Some levels contain no fuel, so you must rely on ladders
and be careful not to encounter any monsters on the ground.

There is also a Phase Shifter built in to your jetpack which
tunnels through bricks. Some bricks are denser than others and
require more time to break through. Grey stone is solid and cannot
be phased. There are also other items that can be affected by the
Phase Shifter. You'll have to experiment to discover what they
are.

There are teleporters that transport you around the level, and
barriers that block your progress. These barriers are deactivated
by pressing buttons of the same color. Activate buttons and
teleporters by pressing down while touching them. Monsters can
turn the barriers on and off by moving over colored floor switches.
There are moving platforms and ladders that can help or hinder you.
Icy bricks make it hard to walk, and some bricks are covered with
sludge, slowing your progress. Monster Stunners, Shields, and fuel
appear randomly for a quick player to retrieve. The Stunners make
the monsters harmless and paralyze them momentarily. Shields
protect you from monsters, spikes, and all other hazards.

If I could rate this game, I would give it a 9 out of 10!
