Skill System and Save/Load Functionality

This update details the introduction of the skill system and save/load functionality in *World of Sopho: A Pup's Adventure*.

## Skill System

A skill system has been implemented to provide character progression for Sopho. As Sopho engages with the game world, he will gain experience in various skill categories. These skills are designed to influence different aspects of gameplay, including exploration, interaction, and combat.

The skill system allows for player customization and impacts Sopho's capabilities. Skill point allocation will affect Sopho's performance in corresponding areas, offering strategic choices for gameplay.

## Save and Load Functionality

A save and load system has been integrated, enabling players to save their game progress. This feature allows players to resume their game from a previously saved state. The saving process is designed for efficiency, providing a seamless experience for players to manage their game progress.

## Inventory Stacking

To improve inventory management, certain items can now stack up to a maximum of 99 units per slot. This change aims to reduce inventory clutter and enhance the player's ability to carry more essential items.

## Future Development

The implementation of these systems provides a foundation for further content development. The skill system will be integrated with upcoming quests and challenges, and the save/load functionality supports extended play sessions.
