CaveMania

Fed up with having Brontosaurus steaks for dinner, Ug the Caveman has decided
to try something new for a change – by navigating nine islands in search of
the three pterodactyl eggs perched high in the mountains, and bringing them
back to his cave one by one, making sure that not one egg breaks along the
way. Unfortunately, searching for the eggs comes at a price. Ug must also leap
across rivers, dodge erupting volcanoes, and use a number of rocks to kill any
land-based predators that get in his way. If he comes into contact with any of
these, he will lose some energy, which can be restored by collecting fruit.
Once Ug has taken all three eggs to his cave, he has to collect some wheels so
that he can travel to the next island.
