BBC Manic Miner was released by Software Projects in 1984.
Compared to the Spectrum original it is slow and flickery, and isn’t quite as colourful, although it plays pretty much identically so isn’t too bad.
One thing to note about the BBC version is that the final two levels are completely different to the original. Level 19 should be the “Solar Power Generator”, but here you get “The Meteor Storm”, which still has the moving reflectors but not the light beam. The final level is still called “The Final Barrier” but is different and much, much harder than the final level in the Spectrum version. They at least give the BBC version something unique to offer, even if reaching them is beyond the patience of most mortals.
