A walkthrough of the ZX Spectrum game, Megaphoenix. There are unlimited levels, and the difficulty stops increasing after level eight. This video shows ten levels being completed. 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
