A walkthrough of the 2013 ZX Spectrum game, Gem Chaser. Collect the coloured gems to match your colour, then change your colour to collect the others. 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 into difficulty, and try again. More info. on the channel "About" page: https://www.youtube.com/user/rzxarchive/about
