Krystals of Zong

In this game, the player must gather the treasures for all eight levels. But
to be able to enter the treasure caverns, the player is required to collect
certain keys, and open the doors in which the key’s color matches the
border’s. These keys are collected in other rooms. If the right key is
obtained, the player is able to pass through the doors, enter the cavern, and
get the treasure. While searching the rooms, you can also get swords that you
can use to kill snakes, bats, spiders, and mummies; and the torches to see.
Besides treasures, other things that you can get in the caverns are pixie
boots which you can get for extra speed, and two potions – one for
teleportation, one for invincibility. There are eight levels in the game, and
going up ladders take you to the next level.
