Classic old school dungeon crawl! Lots of traps, treasure to loot, magic items and spells to obtain (or be killed by). Secret doors and paths creates shortcuts and leads to secret areas. All in all a really good, and well designed classic dungeon crawl! The feel of the adventure is very Appendix N; with the necromantic wizard summoning a djinn, and the not-so-2025 naked princess in distress.
The text does however seem incredibly small. It makes no difference on screen, but I don’t think my eyes would enjoy running this adventure if I printed it out as an A5.
