--- Game Rules ---
○ Title
• When starting the game, choose your difficulty level.
- Super Easy…Only Level 4 orbs appear on the launch pad. The size of the orb is equivalent to that of the Hard difficulty.
- Easy…Orbs from Level 1 to 4 appear on the launch pad. These orbs are smaller than those in Hard mode.
- Hard…Orbs from Level 1 to 4 appear on the launch pad. These orbs are larger than those in Easy mode.

○ Basic Controls
• At the start of the game, a new Fruit Orb is launched from the top of the screen.
• Players can control the launching orb using left/right movement buttons, cursor keys, or touch input.
• Press the center button, SPACE key, Enter key, or tap the center area to fire the orb and place it by colliding with the existing orbs.

○ Orb Fusion
• When two orbs of the same level collide, they merge into a new orb that has leveled up.
• The score earned from a fusion is added based on the level achieved after merging.
• Once orbs fuse up to the maximum level (the white orb), no new orb is generated, and it disappears from the scene.

○ Physics Simulation
• Orbs are affected by gravity and fall toward the bottom of the screen.
• Realistic movements are recreated through collision rebounds and the pushing against one another.
• Once an orb has landed and stabilized, or after a set time following its launch, the next orb is prepared.

○ Game Over
• The game ends when there’s no more space to place new orbs or when overlapping prevents a new orb from being generated.
• After a game over, you can check your score and restart from the title screen. If your score exceeds the recorded high score, it will be updated. High scores are tracked separately by difficulty level.
