Ink & potions. Spelling words pays off by part of speech:

• Spell a noun → earn ink (your currency, shown top-left). Spend it at the Stall on the home screen (walk up and press E, or tap SHOP) to grow your satchel.
• Spell an adjective → brew a random potion. These stack up in the HUD.

Drink a potion with 1/2/3 or by tapping its HUD button — each lasts 25 seconds:

• Size — grow bigger, with longer attack reach.
• Speed — move faster.
• Reveal — the minimap shows the whole map and which screens still have letters.

Rewards repeat: re-spelling a word spends its letters again and pays again.

Word of the Day. Each day the Wordsmithy shows a bonus word — always built from letters you've unlocked, so you can always collect what you need. Spell it once for a big ink bonus.

Mad Libris. The lectern right of the Wordsmithy. Restore a story by filling each blank with a collected word that matches the needed part of speech (noun/verb/adjective/adverb). Matching the original word earns bonus ink. A word can be used in a chapter only once, ever — so keep learning new ones. Finish every chapter to add the book to your Wordhoard.

Creatures & the bestiary (B). Out in the field you'll meet more than inklings — pests, cubes, and hazards that drop book-binding materials (paper, glue, thread, wax, leather…). Beat one and its loot drops on the ground, then flies to you when you're close (auto-collect) — but grab it before The Kindle scorches it. Cheese heals a heart. The bestiary logs every creature you've beaten and reveals more (stats, drops, lore) the more of that creature you defeat.
