Mobile Escape: Family Secrets

This is the first episode of a 12-part series; each episode is delivered in a single standard-sized envelope. This format has the great advantage that the game is very reasonably-priced, and doesn't attract hefty P&P or import duty charges when delivered from its native Canada.  It also means that the components are relatively small, and largely paper-based. But the production quality is good, and there is variety in the styles of printed matter - a map, a cut-out compass and coins, some letters etc.
Both the theme ("long forgotten pirate treasure inheritance") and the puzzles themselves were relatively predictable and a bit cipher-heavy for more liking - largely relying on process over any significant "A-ha!" moments. However, it provided around 2 hours entertainment for under £10, which was very good value for money, and I look forward to playing the next instalments in the series.
