Completed the entire storyline. Saved after the credits.
Side "worlds" are almost untouched
You can fly around the world and complete side quests.

Save with a large list of weapons, almost all costumes and hairstyles of Gustave and Lune, as well as with the maximum number of some key items and a lot of chrome.

Installation:

If you have the Steam version of the game:

In the Steam library, right-click on the game and select "Properties...". On the General tab, disable the Cloud Sync option
Open the folder at the following path: C:\Users\[YourUserName]\AppData\Local\Sandfall\Saved\SaveGames
Download the save and extract the contents to the Saved folder or drag the contents to SaveGames, having previously made a backup copy of your save
I think you'll figure out what's what :)
If you don't have the Steam version of the game: follow the installation order - skip the first step

P.S.
The game was played with cheats... so there may be a resto level somewhere :)
(Sometimes resets points)

The game is good but the combat didn't work out... that's why I played with software.
But otherwise I boldly recommend playing it.
p.s. very long and boring cutscenes
