Expand rooms to 2× viewport width and add enemy patrol movement

[Copilot]

The game rooms were exactly the size of the viewport (384×216), leaving no space for the camera to scroll and making the 64×64 player fill ~30% of screen height. Enemies had no movement logic.

Enemy patrol (Enemy.gd)

• Added x_min, x_max, speed exports matching the MovingBlock pattern
• _physics_process shuttles the enemy between bounds; sprite flips on reversal
• @onready var _sprite replaces fragile $Sprite inline references

@export var x_min: float = 0.0
@export var x_max: float = 100.0
@export var speed: float = 60.0

func _physics_process(delta: float) -> void:
    position.x += speed * _direction * delta
    if position.x >= x_max:
        _direction = -1
        _sprite.flip_h = true
    elif position.x <= x_min:
        _direction = 1
        _sprite.flip_h = false

Room expansion (Room0.tscn, Room1.tscn)

• Both rooms expanded 384 → 768 px wide (2× viewport, matching original GameMaker room-to-view ratio)
• Right wall moved x=376 → x=760; floor widened to 768 px
• Second half of each room populated with 3 new platforms, 3 diamonds, 1–2 additional patrolling enemies, and a second moving block
• Camera limits (limit_left=0, limit_right=768, limit_top=0, limit_bottom=216) set per room so the camera scrolls without showing outside bounds

Camera clamping (GameCamera.gd)

Lerp target is clamped to the camera's limit bounds before applying, preventing rubber-banding near room edges:

var tx := clampf(_target.global_position.x, limit_left + half.x, limit_right - half.x)
var ty := clampf(_target.global_position.y, limit_top + half.y, limit_bottom - half.y)
global_position = global_position.lerp(Vector2(tx, ty), lerp_speed)

Death area (DeathArea.tscn)

Collision shape widened 384 → 2000 px so a single instance covers any room size.

Original prompt

Pull request: #3

The assets are now loading and movement feels better but the scene is too small compared to the player. None of the enemies are moving but I have a feeling it's because of th scene size
