Game designer focus
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.

Game Designer Guide to Koin Purchase Recovery for WebGL Games
Use a browser-based playable build to work through purchase recovery for WebGL games. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
Define the WebGL games scope
Platform context
Design for the input, layout, interruption, and return behavior players expect from WebGL games.
Prototype boundary
WebGL rendering and commerce state need separate failure testing.
Purchase Recovery in practice
Starting state
Show one item that remains optional, its preview, precise Koin price, available Koin balance, and ownership rule in a layout suited to WebGL games.
Main task
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Keep each change visible to the player rather than hiding it in technical state.
Recovery
Make a player cancellation, too little Koin, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Role decision
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.
Solve the purchase recovery details
Protect rendering performance
For a game designer, this purchase recovery prototype should make every player action and result shown in the game easy to evaluate. Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Open and close the interface during GPU-heavy scenes, then monitor input, frame pacing, and canvas recovery. A commerce overlay should not leave the game loop paused or controls captured unexpectedly.
Coordinate DOM and canvas state
Make the selected item and outcome visible in both interface and gameplay context. Handle focus loss, pointer lock, fullscreen transitions, and a resized canvas around confirmation and return.
Exercise context recovery
Simulate refresh, background suspension, and a lost rendering context. The player-facing purchase result should reconcile separately from graphics recovery and must never duplicate an item.
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.
Keep pending understandable
If delivery is interrupted, explain whether the result is pending, safe to retry, or already complete. Do not show both failure and success. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Make retry idempotent
Repeated clicks and reloads should resolve to one purchase result. The player must never receive duplicate items or lose Koin twice. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Return to a safe game state
Cancelling the action, an insufficient balance, and recoverable errors should preserve progress and offer a clear return or retry action. Test that behavior using WebGL games. WebGL rendering and commerce state need separate failure testing.
Prototype the player journey
1. Set the platform context
Choose the input and screen behavior for WebGL games. State the platform limit beside the prototype brief.
Result: An honest scope
2. Map purchase recovery
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Describe the player action and visible response at each point.
Result: A clear purchase recovery sequence
3. Add the Koin choice
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
4. Apply the game designer lens
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
5. Test return and recovery
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
Generate the WebGL games prototype
Prompt 1
Create a GPU-accelerated browser canvas for a game designer. Focus the IAP prototype on handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. 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: WebGL rendering and commerce state need separate failure testing.
Prompt 2
Keep the item optional. Show its full price in Koin, Koin balance now, confirm, cancel, low-balance, success, visible delivery, and reload states.
Game Designer test checklist
- The purchase recovery sequence feels natural for WebGL games.
- The game designer can make the intended decision from the playable result.
- The item, Koin price, and balance appear before choosing confirm.
- Cancel, not enough Koin, pending, success, and reload have different outcomes.
- The page states this boundary: WebGL rendering and commerce state need separate failure testing.
- Play cancellation and a full session without purchase. Check timing, value, competitive impact, and whether the item matches the delivered result.
Limits for WebGL games
- WebGL rendering and commerce state need separate failure testing.
- This guide uses a direct Koin transaction for one optional game item. It does not create a subscription or recurring charge.
- The result is a prototype that runs in a browser. Native billing, identity, durable entitlements, security, refunds, and store approval need separate implementation.
- SEELE does not provide payment analytics, tax tools, payout reports, or guaranteed revenue through this flow.
Frequently asked questions
What does purchase recovery mean here?
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. The result is shown as a playable Koin flow.
Is this a subscription?
No. The player spends Koin directly on one named item or unlock.
What happens if the player cancels?
Return to the same game state without spending Koin or delivering the item.
What if the Koin balance is too low?
Explain the shortage, preserve progress, and do not deliver the item.
Does this include payment or revenue reports?
No. It covers the player-facing purchase experience, not financial reporting.
Is the prototype ready for a native store?
No. WebGL rendering and commerce state need separate failure testing.
