I can not save my progress in the game.

[MiwaNaru]

I've tried countless times, but when I go back to playing always starts from the beginning.
How do you save the progress of this game?

[jDog]

The red cyrstals are save points.

[Arthur]

There's not auto save. You have to right-click the red crystals.

If that doesn't work, try to run the game with system Administrator privileges.
