I purchased The Gem Prison of Zardax from a recommendation on an excellent puzzle dungeon, and it is billed as such: 'Puzzle adventure'. Overall the premise is interesting, but the puzzle aspect is a bit of a non event. There is but a single way out of the dungeon, and although some of the encounters are interesting, many are lacklustre. Scrap princess has some excellent art (if you are inclined towards that style), and in particular I really liked the mother in room 19- awesome. Only a few of the ideas resonated with me, and nothing significant here to mine for my own game. There are runes in each room that give clues as to the contents of each room, which is cool, but since there are no clues about how to use them or what each stands for, by the time the party has explored most of the rooms will be when they figure out what different aspects stand for, so they are a bit of a non-event. Format and content otherwise all good- 48 pages, great cover art (uncredited?). Overall Firmly average. This is a linear adventure hidden behind some randomness- Zzarchov Kowolski has a good reputation for interesting adventures, but not executed particularly well here. If you are looking for a different example of a puzzle dungeon with some chops, try Ex Libris in Dungeon#29. If you are looking for a non sequential linear extra dimensional trap for your PCs, Gem Prison of Zardax is definitely worth a look, just not suited to my purposes.
