This is a 3D crime scene game where the player finds clues to solve a murder. I improved a prebuilt version by adding player movement, mouse look, and an interactive cursor. I built a clue storage system with store/drop buttons and linked it to dialogues and animations. I also added a timer to track how long the player stays in the room. I cleaned and optimized the code to make it easier to manage. The final result is a smooth and immersive mystery game.
