Here are all the screens from Matthew Smith‘s original classic ZX Spectrum platform game (and sequel to Manic Miner), Jet Set Willy. All 61 of them. Plus the ending after completing the game.
Of course, you had to cheat to complete the game as it was bugged and prevented you from finishing. Later versions of the game eradicated that problem, I believe.
Jet Set Willy is still a game that excites games-players today, as can be seen by the many homebrew variants of the game that can be found online. It is still a marvellous game, in spite of its age, and the controversy behind the bugs.
