LostDune: A 2D Platformer Game Using Godot 4 Engine with Finite State Machine Architecture

This paper presents the design and implementation of LostDune, a 2D side-scrolling platformer game developed using the Godot 4 game engine. The project demonstrates the practical application of fundamental computer science concepts including Finite State Machines (FSM) for character behavior management, kinematic physics simulation for responsive player movement, and modular software architecture using object-oriented design principles. The game features three progressively challenging levels with distinct environmental themes, implementing core mechanics such as precise platforming, enemy AI with patrol behavior, collectible systems, and persistent data storage. Performance analysis demonstrates stable 60 FPS gameplay with input latency below 50ms, validating the efficiency of the Godot engine's 2D rendering pipeline. The development process emphasizes
