Need to finish a horror game on Unity.

The horror game on Unity needs to be completed.
The basic project is already in place: the map and some mechanics are ready. Help is required to bring the game to a more finished and atmospheric state.

What needs to be done:

• main menu;
• settings;
• language switch Russian / English in settings;
• autosave;
• basic narrative delivery;
• horror events and jump scares;
• prepare the structure for voice acting;
• beautiful and user-friendly text presentation in two languages.

About the game:

This is an atmospheric horror focused on tension, events, plot, and frightening moments.
It is important that everything looks cohesive: the menu, settings, language, saves, jump scares, and plot should work as a unified system.

What is important:

• the project is on Unity;
• the code must be clear and not broken;
• preferably, everything should be convenient for further development;
• we need a person who can not only write code but also help carefully bring the project to a playable state.
