It appears that Crazy Climber and its two versions was not an isolated case within the short history of Ventamatic.
It hapenned the same with this Autostopista Galactico (Galactic Hitchhiker).

The version we are reviewing, released in 1983, was followed a year after by another one, improved with the addition of a graphic designer to the team. As improved as the game would look completely different.

Very simple graphics and almost total absence of sound are the main technical features you are going to find in a game that is not very fun.
