Prototype the journey before Blueprints
For a game designer, this inventory delivery prototype should make every player action and clearly displayed outcome easy to evaluate. Write how to connect successful purchase to a visible owned or quantity state. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use the browser build to settle the offer moment, information order, and recovery behavior before assigning Unreal UI, gameplay state, service, and platform-commerce work.
Separate concept from provider setup
List ownership, persistence, online services, native commerce providers, refunds, security, and certification as independent tasks. This page does not configure an Unreal purchasing integration.
Create engine expected scenarios
Carry the exact player-visible paths into later Unreal testing: decline, insufficient Koin, pending, interrupted delivery, owned state, and reopen. Verify one result across UI and gameplay state.
Judge the offer in the core loop
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.
Make the player promise concrete
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.
Review the moment of choice
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.
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 Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers 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 Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers 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 Unreal prototype teams. SEELE does not claim to configure native Unreal commerce providers from this page.
