What I Accomplished
Assembled the Main Scene: Successfully created a master playground scene (Main.tscn) and instanced both the player and the enemy into it so they exist in the same world.

Player Controls & Mouse Aiming: Implemented a movement script for the player utilizing arrow keys, and added logic allowing the player’s gun to smoothly track and look at the mouse cursor.

Camera System: Added a Camera2D node attached directly to the player so the game window viewport tracks the player dynamically.
