The Pyramid (1983)

Released for the ZX Spectrum way back in 1983, Fantasty Software's "The Pyramid" was amongst the earliest batch of titles for the system to move away from simply being a conversion of one of the current arcade games doing the rounds. Coded by Bob Hamilton, with assistance from Darren and Ian Hamilton, the game saw you control Ziggy, as he descended through the 15 layers of The Pyramid. A pure machine code title, the game featured smooth, well animated sprites, and arcade style gameplay.
