Rabbit Transit
Rabbit Transit is a 1983 game by Starpath for the Starpath Supercharger, an add-on for the Atari 2600 that loaded games from audio cassettes. It was designed by Brian McGhie. You guide a rabbit across a busy meadow in a Frogger-like first stage, then hop around colour-changing ledges in a second stage that plays a lot like Q*bert. You can play it here in your browser, with no add-on or tape deck needed.
