A pastiche of the yuppie fad of the 1980s, O.K. Yah! is a side scrolling game released in 1988 by Pirate Software Ltd. The goal is to traverse several colourful levels and make it to the 'Intergalactic Stock Exchange' on your hoverboard by avoiding enemies such as killer mobile phones.
The idea of this arcade game is deceptively simple: Guide a marble down a path without hitting any obstacles or straying off the course. The game is viewed from an isometric perspective, which makes it harder to stay focused on the direction the ball is to follow. There are tight corridors to follow and enemies to avoid. There is a 2-player mode in which players must race to the finish; otherwise you're racing against the clock.
A freeware game distributed in the late 80s via Macintosh's HyperCard system. It is a point-and-click adventure game where, after spending time in cryostasis a lone astronaut crash lands on earth. Seeking shelter in an abandoned mall the player must find a way out and figure out what happened to the Earth.
