Courtney Granner was a graphics artist at Atari. On the site he is credited for Pengo, the 1984 2600 version of the arcade game by Coreland and Sega, in which a penguin kicks ice blocks into the Sno-Bees. Granner drew the graphics, Mark Hahn programmed it, and Andrew Fuchs and Jeff Gusman made the sound, which made it one of the first 2600 games built by a team rather than a single programmer.

Pengo is Atari’s 1984 Atari 2600 version of the 1982 arcade game made by Coreland and released by Sega. You are a small penguin on a field of ice blocks, and your job is to crush the blob-like Sno-Bees by kicking blocks into them. It is a maze game where you reshape the maze yourself, which makes it feel quite different from Pac-Man and its many imitators. You can play it here in your browser, with nothing to install.
