uide the Hero to the lowest part of each cave to find the lost
miner. Some caves may also have horizontal tunnels, so if you end up flying just above an
acid lake, try to find an exit on the left or right end of the screen.
To destroy the doors that will bar your way, pull down on the joystick to drop a
grenade, then run away to protect yourself from the explosion. If you are running out of
bombs, use the laser to get through the door. It will take longer to crumble, so beware of
the time limit.
Avoid any contact with lava walls or doors, and of course kill any unfriendly animal
like bats, spiders, snakes and insects.
