ドンキーコングJr. — About this game
Junior must rescue his father Donkey Kong from Mario. Alongside platform jumps, climbing and descending vines help avoid enemies. Holding two vines with both hands makes climbing faster; holding one allows a faster descent. Rather than always fleeing upward, change your grip and speed to open a route. Drop fruit to defeat enemies, then push the keys upward in the final challenge to open the cage. Check the landing platform and next vine before jumping, and watch the distance to your pursuers.
