Atari released this isometric video game in 1983. The player uses a trackball and a jump button to control Bentley Bear as he collects gems along the paths of the castles. Wearing the magic hat allows Bentley to kill the Wicked Witch, Berthilda. Her gem eaters are vulnerable only while they are eating. Bentley can jump over the trees to stun them for a short time. Other enemies cannot be killed, so Bentley must avoid them. Secret warps take Bentley to higher levels.
