Crystal Castles atari 2600

Bentley Bear is trapped in the crystal castles! To get out, he will have to collect all the gems located throughout the castle. The game is played with an isometric view of the cross-platform castle. When Bentley collects all the gems in the current castle, he moves on to the next, more difficult castle. Roaming the castles are a wide variety of dangerous creatures, which Bentley should avoid. Occasionally, a magic hat will appear. If Bentley recovers the hat, it will be temporarily invincible to the inhabitants of the castle.
