We have spent significant effort trying to improve this, and are aware that on some platforms it's still not where we or players would like it to be.
As of version 2.3.0, there is an option to adjust the frequency of auto-saving. You can see it in the Options menu, under the Gameplay section. Consider unticking that checkbox so that the game auto-saves less frequently. This will let you play longer between such interruptions. However:
- If the game seems to crash frequently on your device then you might not want to do this as you stand to lose much more than 5 minutes of progress when a crash occurs.
- Please make extra sure to end your play session by opening the Options Menu and clicking one of the two Save buttons. Since there will be much longer between auto-saves, you could lose much more than 5 minutes of progress if you accidentally forget to save the game.
