Greetings issily,
Welcome to the Apple Support Communities!
I understand that you are trying to recover data from a game that you have previously played on your iPhone. For the best information on if this may be possible, I would suggest contacting the developer of that application. For information on how to contact the developer, please refer to the attached article below.
If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support
Contact the app developer
If you see this issue again, contact the app developer for help:
- Find the app in the App Store.
- Tap the app, then tap Reviews.
- Underneath App Store Customer Reviews, tap App Support.

Cheers
