Last April, Retro Gamer and writer 'Reverend' Stuart Campbell spent four pages on Matthew Smith's Manic Miner, specifically discussing the classic platformer's non-Spectrum editions and all the extra levels introduced in those ports.

Inspired by the article, the homebrew programmers at Headsoft, who also coded the excellent Warhawk DS, gathered all those stages from the commercial Manic Miner ports and released the collection for free on the Nintendo DS (playable with an emulator or homebrew device).

"The tale of Miner Willy and his incredible adventures in the mines, and then the mansions, of Surbiton is legend. But like all legends, it doesn't tell the whole story. Most people know Willy simply as a digger who got lucky and lived happily ever after in decadent luxury. Far fewer know the secret - suppressed for quarter of a century by the government - of how he also saved Planet Earth from alien invasion.

It wasn't until an eccentric but dedicated historian writing a paper for a renowned academic journal (Retro Gamer issue 63) pieced together the complete saga of Willy's heroic exploits from fragments of scattered evidence - in the form of obscure retellings of the 'Manic Miner' folk fable in ancient languages readable only via long-obsolete machines - that the whole truth was finally revealed."

Manic Miner In The Lost Levels features a total of 50 stages, arranged in three sections. The Lost Levels portion includes 20 levels that were added (or modified) for the Manic Miner versions released on Oric, BBC Micro, Dragon 32, Amstrad CPC, and GBA.

After completing The Lost Levels, players can access Willywood, a standalone 10-level game with original stages designed by Headsoft. They can also unlock 20 bonus stages that are "a mixture of original levels and classic levels from both Manic Miner and other related games" by finding secret areas scattered around Willywood and The Lost Levels.
