The code has been refactored to clarify the functionality of various components and improve type hinting. Documentation for methods has been expanded. The return types of to_dict methods in several classes have been changed to return CounterState. The Counter class now correctly handles cases where an Item or Iterable[Item] is occupied. An unnecessary Boolean attribute, all_players_ready, has been commented out. Manual normalization of orientation vectors has been introduced.

The classes across several files have been modified to improve clarity, provide better comments, and refine attribute representations. This commit involves refactoring the item, effect, and player classes to include more detailed descriptions and user-friendly outputs. The change also simplifies some methods and eliminates redundancies for cleaner and more efficient code.

Better management of when keyboard or controller button to continue is pressed. Updated thank you screen.

This update adds several darker shades of gray (from GRAY2 to GRAY9) to the game_colors file. These additions provide more color options for game elements, ensuring a better visual experience for users. The color values have been moved for improved organization and readability.

Added HTML color preview comments for each color constant in the game file. This should provide better visualization during code read-throughs, aiding in understanding and debugging process. Replaced generic color name in the blue color preview with the specific hex value.

In the cooperative_cuisine/__init__.py, the action_type in the action object is updated to PICK_UP_DROP from its previous value PUT. This change accommodates a need for more specific player actions.

Improved the clarity and precision of language used in the CHANGELOG.md file. Specifically, this includes modifying ambiguous sentences and rectifying grammatically incorrect sentences to enhance overall readability.

The PAUSED variable, which was unused, has been removed from the codebase to improve readability. Docstrings were added to multiple existing methods and instance variables in the environment.py file for better understanding of their functionalities. This change will make it easier for developers to understand the purpose and usage of the various methods and variables, ultimately smoothing the development process.

The ActionType.PUT has been replaced with ActionType.PICK_UP_DROP across all instances in the codebase. This change aligns the action name with its actual function, making the action more intuitive and the code easier to understand. This update also includes minor modifications in comments and function arguments to reflect the new action name.
