A solid little introductory adventure that can be played in a single session. Beautiful maps by Dyson Logos (I'm a big fan of his clear line style). It does, however, have one significant flaw: the monster encounter difficulty is absurdly overpowered for Level 1 or 2 PCs in 5E (assuming a typical party size). One room contains eight (!) orcs who "won’t hesitate to attack and subdue the PCs." Eight orcs is a "deadly" encounter for Level 4 PCs, never mind Level 1. I'll probably run this for my son and his friends, but I'll have to nerf most of the encounter CRs beforehand.
