In Sine Requie,  to valorize players choices, the game auto-saves every time a narrative section is over. 
In case of the Inquisitor Mazzoni unfortunate departure, your adventure will re-start a step before the fatal one. 

Moreover, multiple chapters compose the story and it is always possible to load back at the start of the current one, at least at lower difficulty settings...

Patch Notes:
The Inquisition is admired by the perseverance of all players and content creators who bravely played the Demo up to the end without any save game option!

- Added SaveGame system to the Demo. Note that restarting the current chapter means to start a new game ( the Demo is one chapter only!)
- Added possibility to change language at any point in the game
- Added audio general volume
- Small bug fixes
