Pengo (Japan, not encrypted)

Pengo is an action game set in an overhead maze constructed of ice blocks. The player controls Pengo, a red penguin that lives in the Antarctic and fights the blob-like Sno-Bees. The objective of the game is for Pengo to survive a series of rounds by eliminating all Sno-Bees, while amassing bonuses by bringing together the three diamonds dispersed in the maze.
