LEVEL 9: TOMB OF TIHOCAN

ROOM WITH LION, GORILLAS & SPIKES: Stay on the step at water level until
you've killed the lion lurking in the room. In the U-shaped passageway on
the side of the room opposite the spikes you'll find a switch. Use it to
open a door above and awaken 2 gorillas. Return to the spike room and climb
into the alcove and onto the step. From here you should be able to kill the
apes. (There's also a save crystal here in the PSX game.)
When they're dead, take a standing jump to grab the floor above and pull up.
Cross to the gap above the spikes. Take a standing jump to grab the crevice
to the left of the doorway and traverse right until you can pull up. Enter
the room and pick up a large medipak and a GOLD KEY. Take a standing jump
from the doorway over the spikes. Then drop down into the room below.
