CRUST is made by one person. You will get a reply from an actual human — just not always a fast one.
Email support@dotmixgames.com. The things that make a bug fixable rather than mysterious:
CRUST stores your progress on your device. It is not backed up to any cloud service, so uninstalling the game deletes your unlocks and van progress permanently. Moving to a new phone does not carry your save across.
Every part of the game works with no connection. If something behaves differently offline, that is a bug — please report it.
Purchases are handled entirely by Google Play and the App Store, not by us, so refunds have to go through them:
We cannot issue refunds directly, and we do not receive your payment details at any point.
What the game records, and where it goes: privacy policy. Short version — anonymous gameplay statistics, no personal data, no ads, no trackers.
