Yuphex instructions:

F1: display these instructions
F2: status
F5: Save game
F6: load game
You can only save one game at
a time. Save game allows
people who want to make the
game easier to save their game
every two seconds and load
right away if they die. It is
entirely possible to beat the
game without saving.

You start with 10 lives.
Whenever you lose a life, you
have to restart the level.
You also start with 255 hit
points.  Whenever you're hit
by an enemy, you lose some of
those hit points.  If you lose
all of them, you die.
Food helps replenish lost
hit points.

Moving around the
Yuphlaxian System:

Use the up, down, left, and
right keys to move your
spaceship. In gravity-free
space, all your movements
build up momentum. That's why
You don't stop moving when you
stop pressing an arrow key.
To enter a planet(or the sun),
just touch it.

In the close up planet views,
the arrow keys move your
spaceship, but without
momentum. To land, go up to
the area on the planet that
looks "uncommon", like the
dark hole on Yuphex.

When You're walking on the
planets (except for Zip),
these are the keys to use:
left: walk left
right: walk right
up: jump straight up
Up-right (Pg Up):
jump up and to the right
Up -left(Home):
jump up and to the left
' ' Space Bar: spit green goo
You will spit in the direction
that you most recently moved.
If you find a shield piece,
press P to pick it up.

On Zip, all eight arrow keys
(including the diagonals) make
you roll in those directions.
When you have all 4 shield
parts, just fly into the sun
and touch the bomb to
disarm it.

Note: the extraordinary
jumping power of the character
can overload the graphics
engine, causing the game to
freeze and the character to
move to a different place on
the screen and begin to float.
At this time, the only way to
stop this bug is to save your
game frequently.

Another Note:  the character
will jump the highest when the
arrow key is held down. For a
smaller jump, tap the arrow
key. Also, at some points in
the game, it is necessary to
change direction in mid-air by
holding down the up key and
then holding down the up-right
or up-left key(or vice versa).
Practice it a few times to get
the hang of it.

Yet Another Note:  In case you
missed it, your only weapon is
your spit (Space bar).
