The tutorial got a pass, straight from player feedback:

- 🍬 New chapter: SUGAR. Five steps now — Brew Tea → Sugar → Serve → Clear → Toilet. You learn to fill the table's sugar bowl; tea served to a table with an empty bowl leaves the customer unhappy.
- 👤 One customer only. No pile-up while you are learning — you finish the lesson with a single guest.
- 🚽 The toilet lesson actually runs now. The customer no longer finishes his tea and walks out: he heads to the toilet, and makes a mess of it. That is where you learn to grab the cue and settle the bill.
- 🫖 The boiling-water step points at the right thing. The marker now highlights the samovar's body; the little chrome tap in front fills a glass, not the teapot.
- ⌨️ F1 really hides the tutorial receipt now, and in a normal game (single player or co-op) the receipt no longer appears at all.
- ❓ The tutorial is offered once, on first launch. Skip it and it waits for you on the main menu under TUTORIAL.

Interface

- 🖱️ You can finally see what's clickable. The row under your cursor is marked and buttons get a lit frame — the old highlight was too faint to notice.
- 📏 Fixed a long tutorial line overlapping the one below it.
