Ogrian Carpet is a first-person 'shooter' inspired by Bullfrog's Magic Carpet. The object of the game is to build a castle, collect mana, and destroy your enemies. To build a castle, select a location, look at the ground, and cast the build spell. Note, you cannot build castles very close to water or other castles. Your castle starts out small, with only one turret. As more mana is added to your castle, it will gain more turrets. Each turret adds another crane to your castle's defense and another spell to your arsenal. Basically, the game consists of fighting for control of mana. Whenever you encounter another wizard, shoot them with fireballs. If you hit them enough, they will "die" and be sent back to their castle. You are then free to claim all the mana in the area for yourself. Once all the mana has been claimed, attack your enemy's castle to get mana out of it so you can claim it for yourself. Once you enemy's castle is out of mana, you can eliminate it by killing it's heart. When all of your opponents have been banished, you've won.
