I fixed the errors with textures and materials, so that they now have an aesthetic appearance that matches this style of play.

1. Changed textures and materials.
2. Shadows have been removed (there are no shadows in the game, and they should not be in the game at all).
3. Fixed a bug with the lighting and textures of Suza
A good example:

Before	After

4. Now the dark room will be darker than before.
A good example:

5. The house has changed.

6. Changed the size of the textures of the characters faces.
7. Fixed the gift model in the main menu of the game.

8. Now the gift and the doll have become bright.

These changes slightly changed the appearance of the game and began to please the eye.
