An old trimetric-style platform game developed by Atari in 1983.
In this great classic platformer with trimetric projection the player has to control the cartoon bear Bentley Bear with the aim to collect as many crystals located on castles. Doing so he has to avoid or defeat several enemies. Some enemies also collect the gems, that is why the player gets a bonus if he catches the last crystal.
