Repton for the BBC Micro is a classic digging/puzzle/maze game written by Tim Tyler and published by Superior Software in 1985. The game is usually described as a Boulder Dash derivative, and while it’s true that its author was influenced by Chris Grey and Peter Liepa’s classic game, he hadn’t played it before he wrote Repton – he’d reportedly only read a review about the game in a magazine. Repton is sufficiently different to Boulder Dash to stand on its proverbial own two feet, but the similarities are obvious and drawing comparisons is unavoidable.
