The game
Do I need a connection to play?
No. The whole run works with no connection.
Do I need an account?
No. There is no login and no sign-up.
Which devices does it run on?
Android devices, through Google Play, and iPhone, iPad and Mac, through the App Store. Computers running Windows or Linux are coming soon.
Which languages?
English, Portuguese, Spanish and Russian.
Are there in-app purchases?
No. Interregnum is paid once, in the store, and sells nothing afterwards: no currency, no favours, no undo. On Google Play and the App Store it costs US$2.99, and refunds follow the store's policy.
Does the game have ads?
No. None, in any store.
