Game Designer guide · Unity Prototype Teams · Koin purchase UX
Use a playable browser prototype to work through purchase confirmation for Unity prototype teams. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.
Design for the input, layout, interruption, and return behavior players expect from Unity prototype teams.
SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Show one item the player may decline, its preview, precise Koin price, balance before spending, and ownership rule in a layout suited to Unity prototype teams.
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Keep each change visible to the player rather than hiding it in technical state.
Make cancelling the action, an insufficient balance, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use the prototype to resolve player-facing questions before creating platform integration tasks.
For a game designer, this purchase confirmation prototype should make every player action and clearly displayed outcome easy to evaluate. Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Validate item value, wording, state order, and player recovery in the browser before translating behavior into Unity scenes, prefabs, services, and platform-specific implementation tasks.
Identify UI states, game-state ownership, durable entitlements, native billing adapters, security, refunds, and test environments. The playable page does not configure Unity IAP or produce a store build.
When a Unity version exists, replay the same cancel, insufficient Koin, interruption, success, delivery, and reopen scenarios. Match player outcomes rather than copying browser code or assuming parity.
Run the game without opening the purchase choice, then run it with the item. Compare pacing, motivation, difficulty, and recovery so the offer supports play instead of repairing frustration that was added deliberately.
Describe what changes on screen, how long it lasts, where it appears, and what remains available without it. Replace value labels such as better or premium with rules a player can observe.
Check what the player was doing immediately before the offer and where cancel returns them. The item should arrive after enough context to understand it, but never during a time-critical or emotionally pressured action.
The confirmation should repeat the selected item, exact Koin amount, balance before spending, remaining balance, and ownership rule without introducing a different offer. Test that behavior using Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Use distinct actions with clear labels and enough spacing for the target input method. Returning to the game should never spend Koin. Test that behavior using Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
After confirmation, show a pending state and disable repeated input until the result is known. A slow response should not create duplicate grants. Test that behavior using Unity prototype teams. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Choose the input and screen behavior for Unity prototype teams. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Describe the player action and visible response at each point.
Result: A clear purchase confirmation sequence
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership.
Result: Game designer focus
Play cancellation and a full session without purchase. Check timing, value, competitive impact, and whether the item matches the delivered result. Repeat the test after interruption and reload.
Result: A stable prototype
Create a design reference for a later Unity implementation for a game designer. Focus the IAP prototype on show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Use a direct Koin item transaction with preview, exact price, confirmation, cancel, insufficient balance, success, delivery, and reload behavior. The game designer must be able to connect the offer to the core loop and player motivation. Do not add subscriptions, payment-provider UI, revenue analytics, or native platform claims. State this boundary: SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
Keep the item optional. Show its precise Koin price, balance before spending, confirm, cancel, low-balance, success, visible delivery, and reload states.
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. The result is shown as a playable Koin flow.
No. The player spends Koin directly on one named item or unlock.
Return to the same game state without spending Koin or delivering the item.
Explain the shortage, preserve progress, and do not deliver the item.
No. It covers the player-facing purchase experience, not financial reporting.
No. SEELE does not claim to configure Unity IAP or ship a native Unity store build from this page.
