Doctor Bimbo’s Lab

Playing a doctor with a one-track diagnosis, you buy ingredients and mix potions with a single therapeutic goal: bigger assets on every patient who walks in. It's a blunt premise played completely straight, which is most of the joke.

The loop is simple text-based crafting: purchase ingredients, combine them into a potion, and hand it over. Before you commit a mix to a paying patient, you can test it on your assistant first and watch how she reacts, which doubles as your quality check and your reward for reading the recipe right. Get the formula wrong and you're out ingredients; get it right and the patient leaves considerably more equipped than she arrived.

There's no branching story here, just an expanding shelf of ingredients and patients to work through, so the appeal is entirely in tinkering with potions and seeing who shows up next.
