- Singleton
Used to create a global instance for essential components such as Audio and Framework. - State
Used to toggle between different game states. - Observer
Used in creating a flexible logger that reacts to changes in the game. - Bridge
Used for smooth game integration with the Spring backend. - Facade
Used to simplify the implementation of complex functionalities across classes. - Strategy
Used to dynamically switch between different rendering approaches. - Flyweight
Used to optimize RAM usage during particle rendering.
