A walkthrough of the 2011 ZX Spectrum game, Dex. Paint each of the ten mazes whilst avoiding the baddies. Completed on the fastest selectable level, until it loops around and the speed increases to become too fast to play.
From the recording originally sent by Paul E. Collins 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.
