Fresh off the success of Manic Miner, Matthew Smith returned in 1984 with a sequel that swapped twenty tight caverns for a sprawling, dreamlike mansion of over sixty interconnected rooms. The premise: after his mining fortune funds a wild party, Willy must tidy every last room before his housekeeper Maria will let him go to bed. Naturally, this being a Matthew Smith game, tidying up means near-impossible platforming.

Gameplay

Unlike Manic Miner's self-contained caverns, Jet Set Willy's rooms connect into one sprawling, non-linear map — a swimming pool, a forgotten abbey, a room made of giant gramophone records, a nightmare room that's exactly as unfair as it sounds. You collect glowing objects scattered throughout, with no in-game map and precious little guidance about where to go next.

Technical notes and infamous bugs

The scale is the achievement here — a mansion this size, this varied, on 48K, built on an engine only lightly evolved from Manic Miner's. It's also notorious for shipping with severe bugs, most famously "The Attic," a room that could crash the game outright on certain machines, quickly patched but never quite living down its reputation.

Verdict

Brutally difficult, sometimes unfair, occasionally broken — and adored anyway. Jet Set Willy's ambition and strangeness earned it a place in British gaming culture that its rough edges never managed to dent.
