A very ordinary version of Pengo, but the best to-date for the C64.
The graphics are slow but the Snow Monsters are still troublesome as you try to survive in the ice block maze. Patch has all the usual elements that go to make this such a compulsive game.
You can electrify the boundary fence to kill the baddies or crush them with a well-aimed ice block. Arranging the diamonds in rows gives you a fat bonus.
But keep kicking those ice blocks or you'll catch a fatal cold.
