Professor Spelunkington only has one goal in life: scour all caverns, looking for special, prehistoric treasures or other valuables. Of course this is not without risks: giant, bloodthirsty bats live in the cavern, and he'll have to avoid them. Help this brave professor to get out of this cavern alive, with as many treasures as possible!
Use the left and right arrows or A and D to walk, and C and J to jump. Press X or K to launch a harpoon. Press the up arrow plus X to launch your harpoon vertically. By pressing W and K, you get the same result. This can be very useful when you have to cross a ravine with dangerous, sharp pins.
