Game Mechanics

• The snake speeds up as it eats fruits, making the game progressively more challenging
• The background gradually shifts from day to night as the snake grows
• Each fruit has a different point value: Apple (10), Banana (15), Orange (20), Strawberry (25)
• The "luck" feature gives your snake an 80% chance to auto-avoid collisions
• When the snake hits itself, there's a 50% chance it will cut off its tail to survive
• Score is reduced proportionally when the snake cuts its tail
• Press the opposite direction key to temporarily slow down the snake

Tips & Tricks

• When the snake grows, its skin becomes darker
• The moon phase reflects the actual astronomical day, not gameplay time
• You can slow down the snake by pressing the arrow key opposite to current direction
• Each fruit has a different score value - strawberries are worth the most!
• The luck feature helps your snake avoid collisions automatically 80% of the time
• If you hit yourself, there's a 50% chance your snake will cut its tail to survive
• The more segments you lose when cutting your tail, the more points you'll lose
• Use the tail-cutting feature strategically to escape tight situations
