To provide users with a pleasant and enjoyable world experience, it's essential to rigorously test and then release.

Please test the following items before world review/release:

It's recommended to test using a link that most closely resembles the actual server environment.

- Please refer to the following guide. \[[Testing your World](docId\:O-tFz8sQIMwHLVbBd3fTD)]
:::



## Check Various Settings

- Ensure the order of Scenes in Build Settings is correct.
- In Unity > Project Settings > Player, verify if the Graphics API settings are appropriately set for each device.
- Check your Lighting against our Lighting Setting guide.

## Performance Measurement Using Runtime Profiler:

- If it's a multiplayer world, register friends as testers and have them join up to the maximum capacity.
- Due to memory occupied by each ZEPETO character, not testing beforehand can cause connectivity issues when the number of players increases.
  - Simulate environments with multiple users to test the performance of world servers and clients.

* Please refer to the following guide. \[[Runtime Profiler](docId:-vEsYGmgrkbtL8T1Yl1dv)]

## Data Get/Set Test:

- Storing and retrieving play data in the world is crucial.
- Run through the world's play cycle multiple times to ensure data is stored correctly and previous records are accurately retrieved when restarted.
- It's recommended to implement play data using DataStorage.
  - After release, you can directly delete tester data stored in ZEPETO Studio's DataStorage.

## Item and Product Testing

### In-World Product:

- Ensure products are purchased successfully.
- Confirm that products are correctly added to the inventory after purchase.
- Make sure any feature or effect applied after purchasing works correctly.
- Please consider the World User Experience (UX) when determining appropriate product pricing.
  - In many instances, the primary objective of world play is to earn currency and make purchases.
  - Overly high prices can lead to a loss of motivation to play, which might cause users to leave.
  - Conversely, prices that are too low can result in players achieving their goals too quickly, which can negatively impact retention.



### Mannequin:

- Check if items are displayed correctly on mannequins.
- Ensure that clicking on a mannequin prompts the item purchase window and that purchases work smoothly.
- If it's a multiplayer world, make sure mannequin previews are synchronized.

## Review Criteria Check

### Optimization

- If world play isn't smooth on the lowest spec device, it may not pass the review.
- Ensure you use the optimization guide and Runtime Profiler for optimization.

### Licensing

- If there are licenses for 3D Assets and soundtracks used in the world, please indicate them during the review submission.
- Worlds with licensing issues may not pass the review.
