Dan Dare solution

Make your way to the reeds and cut them down. Enter the subterranean lake
and swim to the left, using the reed as a snorkel. Keep going until you hit
a submerged object and pick it up  it's a highly useful crowbar. Once it's
safely in your possession, swim right and keep aging until you reach a
ladder. Climb up the ladder and walk right until you reach the steps. Go
down to enter the underground cave system. Walk left and keep going until
you find a location with two vines.

Climb down the longest vine, cut off the vine to the left and tie it to the
piece on the right. Climb down the tied vines and when you reach the bottom
walk to the right and open the hatch with the crowbar. Collect the fruit and
climb back up the vine.

Walk right, until you come to a passage 'too narrow for you to pass
through'. Throw the fruit. Stripy will chase after it and return bearing the
torch, which he will duly give to you. Go back to the vine room and climb
down the vine again. Enter the hatch swrtch on the torch and climb out again.

Climb up to the top of the vine and cut it down, then walk to the vine on the
left and climb down until you can go no further. Tie the two vines togother,
then climb down again. Walk left until you find the hatch you opened earlier,
then go through it to enter the Treen's underground complex.

Climb down the long ladder and walk right. Climb down any one of the three
ladders and walk left to find a Treen guarding a closed door. Use the
crowbar to open the door, then walk left. Kill any Treens you encounter
to get special pass cards (you need three of them). Make your way down the
network of ladders and gantries until you come to an unlit room. Use the
torch to find your way about, then go down until you come across two cells
which you should open with your pass cards to free your friends. Make your
way back up to the darkened room and walk to the left you should now be
standing in front of a large laser. Don't use it just yet.

Walk left until you enter a compiex of interchangeable mirrors. There are
three main reactors hidden in the complex. You must set the mirrors so that
when the laser beam is fired by the cannon, it is deflected by the mirrors
to the hole in front of the reactor. Remember to destroy the reactors in
order (look at the numbers stamped on the side of each one). Once you've
blown up all three computers, go up to the third computer where you will
find a door has opened. Walk left, killing any Treens as you make your way
to the Mekon's lair. Lob ten grenades at the Mekon, avoiding his bursts of
laser fire. 

Once you've disposed of the green bonced one you are given two minutes to
escape. There's an easy way out, but that's the bit you've got to figure out
for yourself...
