A walkthrough of the 2012 ZX Spectrum game, Lost in My Spectrum. From the recording originally sent to http://www.rzxarchive.co.uk/ .
Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get in trouble, and try again. More info. on the channel "About" page: https://www.youtube.com/user/rzxarchive/about
UPDATE: A new improved version of the game was released in 2017. A walkthrough can be viewed here: http://youtu.be/c1oK2R5urZE
