Player Experience

Receive notifications about in-game event via email that player provides on intro and can update in Settings. Player can also choose to switch this on or off. Player can also choose the language the notifications are being sent with.

Create a Facebook app, so I could play from within the network, invite my Facebook/Instagram/WhatsApp friends easily.

As a player I'd like to just share an invite link or code or present QR-code to the group of my friends/contacts so they could use it when it is convenient. Optionally I can specify how many times invite can be used or when (after how much time) it expires.

Introduce the system of Achievements and corresponding badges for unlocking those. E.g. upon accumulating first 10 or 20 or 50 units of Trust in TTB etc.
