The TAP file of Andrew Broad's 2004 game "Manic Miner: Neighbours - Allana Truman" contains a secret bonus game "Reverse Manic Miner". It is a version of the classic where you play through the caverns in reverse order, starting in "The Final Barrier" and finishing in "The Central Cavern".
"Reverse Manic Miner" offers an interesting concept, a smart solution to some technical problems which arise with the transformation (thanks to a patch by John Elliott) and a slightly strange playing experience.
An RZX recording of the game can now be downloaded from The RZX Archive.
There is also an additional block of 64 bytes of data called "LordDance" within the TAP files of Andrew's "Party Willy" 48K (perhaps also the 128K version, I can't see it there, though). I don't know how to run it to see what it is. Any ideas?
