*** I have fixed the bug that caused the game to crash on start-up. *shakes fist at MSVS*

CAVE DANGEROUS!

You need to find the prized jewel of the blue!
It's in the caverns. Watch out for bats. They are known to kill humans... like you!
There is a nearby supply store that will provision you with whatever you need. They only accept gold though.

Controls:

Arrows Left and Right --> move!
Button Z --> jump!
Button X --> use currently selected item
Button C --> scroll inventory
