Review the shared family decision
Keep adult guidance visible, avoid guessing who controls the Koin balance, and let a parent or guardian dismiss the choice without changing the child-facing game. Use age-appropriate wording and never imitate consent or child-account systems that the prototype does not provide.
Run a price-comprehension check
Give a new player the offer without explanation and ask them to name the selected item, full Koin amount, available balance, expected balance afterward, quantity or duration, and ownership rule. Let them decline, then repeat with insufficient Koin and a successful choice. Review every place the value appears and remove crossed-out amounts, vague premium labels, unsupported real-currency comparisons, or urgency that distracts from the final cost. The wording on the preview, confirmation, success message, and owned view must describe the same thing. Reopen the game and verify that the balance and ownership shown to the player still match the one transaction they approved.
Keep price and balance together
Place the exact Koin amount beside the visible Koin balance and show the expected remaining balance before choosing confirm. For families and parent-guided players, the experience must use adult-controlled prompts, clear age context, and no child-account assumptions.
Explain duration and ownership
State whether the item is permanent, consumed on use, limited by quantity, or active for a fixed time. For families and parent-guided players, the experience must use adult-controlled prompts, clear age context, and no child-account assumptions.
Remove misleading price signals
Avoid fake urgency, crossed-out prices, unsupported currency comparisons, and labels that hide the final Koin amount. For families and parent-guided players, the experience must use adult-controlled prompts, clear age context, and no child-account assumptions.
