1.6.0 preview 2: new endings

The preview version was updated to 1.6.0-preview.2.

Two new endings were added. It is also now possible to review the endings (by clicking on it).

The internal handling of the save state was updated to take less space, so let me know if you encounter any unexpected behavior when you save or load the game.

If no major issues are reported, I will update the main version in a few days.
