Manic Miner Amstrad CPC

Miner Willy, while prospecting down Surbiton way, stumbles upon an ancient long forgotten mine-shaft. On further exploration, he finds evidence of a lost civilisation far superior to our own, which used automations to dig deep into the earth's core to supply the essential raw materials for their advanced industry. After centuries of peace and prosperity, the civilisation was torn apart by war, and lapsed into a long dark age, abandoning their industry and machines. Nobody however, thought to tell the mine robots to stop working, and through countless aeons they had steadily accumulated a huge stockpile of valuable metals and minerals, and Miner Willy realises that he now has the opportunity to make his fortune by finding the underground store. — Cassette Inlay

Manic Miner is a platform game originally written for the ZX Spectrum by Matthew Smith and released by Bug-Byte in 1983 (later re-released by Software Projects). It is the first game in the Miner Willy series and among the early titles in the platform game genre. The game itself was inspired by the Atari 800 game Miner 2049er. It has since been ported to numerous home computers and video game consoles.

The Amstrad version was effectively the same as the Spectrum version by Software Projects, except that Eugene's Lair was renamed "Eugene Was Here," and the layout of The Final Barrier was again completely different (but is more similar to the Spectrum version than the BBC version).
