Dragon Crystal

Game Only - Great Condition.
 
Dragon Crystal is a dungeon crawler with RPG elements, along the lines of classics such as Rogue or Nethack. 
 
Without relying on a story, the game throws you into a randomly generated world which you should explore carefully - and most importantly, where you must survive! 
 
The complex, maze-like levels reveal their structure only after you cover the corresponding map areas. Your goal in each level is to reach a teleporter which will take you to the next one.
 
There are also a lot of random items scattered around - weapons, armour, money, and food. Money allows you to continue the game if you die, food prevents you from starving.
 
The enemies are visible on screen, and you fight them in real-time combat, moving around and pressing direction arrows to strike with the equipped weapon.
 
You are always accompanied by an egg which will eventually grow up to be a dragon if you have levelled up enough.
