What's in a name? R-Nest is a pseudonym for Q-Bert, the game in which you have to paint the cubes on a 3D pyramid while avoiding hungry monsters. It's a rather good version with some individual features.
R-Nest himself is a cute little figure with an alarmingly big nose who hops around energetically trying to do his job.
His main opponent is Gargal the snake, accurately described in the blurb as looking like 'a mutant bedspring'.
R-Nest's graphics are colourful, but do have that slight haziness which Commodore 64 owners will be familiar with. Sound is a little weak, but this is a game where it shouldn't matter too much.
