Use it as a design reference
For a technical producer, this inventory delivery prototype should make every player action and result the player can inspect easy to evaluate. Write how to connect successful purchase to a visible owned or quantity state. Map preview, confirmation, a player cancellation, not enough Koin, pending, success, delivery, owned, and reload. Give every failure a safe next action. 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.
Write the Unity handoff separately
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.
Compare the later implementation
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.
Name every state and owner
Separate preview, confirmation, pending, success, delivery, owned, insufficient Koin, cancel, interrupted, and reopened states. Assign later production work for identity, persistence, native billing, security, refunds, policy, and monitoring.
Define idempotent recovery
Repeated confirmation, a slow response, navigation during delivery, and reopening must resolve to one result. Record which state is authoritative and how the player can safely retry without another grant or Koin deduction.
Turn the prototype into tickets
Capture the visible behavior first, then create implementation tasks with expected examples for each transition and platform boundary. Do not translate a working browser interaction into an unsupported claim that backend commerce is complete.
Connect success to the item
A success message is not delivery. Place the cosmetic, consumable, unlock, or upgrade in the screen where the player expects to use it. 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.
Show ownership and quantity
Use owned, equipped, unlocked, or remaining quantity as appropriate. The state should match the promise made on the offer card. 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.
Verify delivery after reload
Reload the prototype and return to inventory. The item should remain visible without subtracting Koin or granting a second copy. 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.
