Golden Krone Hotel (2016)

An unknown potion comes with a short list of possible identities, turning a desperate drink into a risk you can reason about. Reading books can narrow the possibilities, while changing sunlight makes the same corridor safe or dangerous depending on your current human or vampire form. This compact, turn-based dungeon is a good starting point for deduction without a vast inventory system. Learn the light and transformation rules first; the bottles still need identifying afresh in later runs.
