Repton 2: one connected world on the BBC Micro

Rather than a sequence of discrete screens, the second game links its areas by transporters into a single space that has to be solved as a whole. A mistake made early can strand the player much later, with no way back and no indication that anything went wrong at the time. It is the entry in the series that experienced players tend to name as the difficult one, and the reason is structural rather than a matter of tighter level design.

The design also explains why the third game returned to discrete levels and added an editor. A single interlocking world is impressive and almost impossible to author for, whereas separate screens can be built, shared and thrown away individually.

It is worth noting what the second game's structure cost it commercially. A single interlocking world cannot be sampled: a demo of one area teaches nothing about the puzzle, because the puzzle is the relationship between areas. Games that can be demonstrated in a slice have always been easier to sell, and that is part of why the third game, built from discrete screens, became the one that spread.

The commercial context is worth stating. This was a full-price release in a market that within two years would be dominated by budget cassettes, and its structure — one large interlocking world rather than a set of samplable screens — is exactly the kind of design that becomes hard to sell when buyers start expecting to try before paying.

The scenarios are named on the record and the way they are weighted is the most exact measurement of difficulty this archive holds for the series. Three are listed — Beginner, Message and Caverns — and the save points are distributed two, three and fourteen across them. Fourteen save points in one scenario is not generosity; it is an admission that the section cannot reasonably be completed in one unbroken attempt, and it puts a number on how much harder the advanced material is than the opening. The same listing offers a level editor and the ability to drop the player's own high-resolution images into a design as puzzle pictures, which is the first appearance in the series of the idea the third game would build its whole afterlife on.

Established here: publisher, machines, the interlocking structure, and current availability through the conversions. Not established: the exact release month, or whether the transporter layout was altered between the cassette and disc releases.
