The ’80s were a strange time, particularly for Atari, who, it seems, were never quite sure how to release or market things properly.
One of their well-received arcade games received an official port to the Atari 2600 and 5200, and the latter version then ended up on the 8-bit Atari computers. Unusually, however, this was published via the Atari Program Exchange or APX, which more commonly published consumer-submitted games rather than licensed ports.
That game was Kangaroo, and it’s an enjoyable single-screen platformer with lots of monkey-punching and fruit-grabbing. It also used to terrify me as a kid and I can’t remember why…
