🎯 Objective

Guide your radioactive snake around the arena. Eat glowing pellets to grow longer and score points. The game ends when your snake crashes — survive as long as you can and chase the highest score.

☠ How You Die

• Hit a wall — on Very Hard and above, walls are solid. On Beginner–Hard, walls wrap (you pass through one side and appear on the other).
• Hit your own body — your snake cannot cross itself at any difficulty.
• Eat a ☠ Toxic pellet — instant death. These appear on Hard and above.

🕹 Controls

• Desktop: Arrow keys or WASD to change direction. Space or P to pause.
• Mobile: Swipe anywhere on the arena, or tap the D-pad buttons. Tap the centre ⏸ button to pause.
• You cannot reverse direction — turning into your own neck does nothing.

📊 Scoring

• Each ● PELLET is worth 10 points × any active multiplier.
• Combo chain: eat pellets within 3 seconds of each other. Each consecutive eat adds +0.5× to the combo multiplier, up to 3.5×. Miss the window and the combo resets.

⚡ Power-Ups

Power-ups spawn randomly after eating a pellet. They expire after 10 seconds if not collected.

★ STAR 2× score multiplier for 8 seconds + 50 pts
⚡ BOOST Speed surge for 5 seconds + 20 pts — risky but rewarding
❄ FREEZE Slows your snake for 6 seconds + 5 pts — great for recovery
◈ SHIELD One free wall collision save + 25 pts (Hard+ only)
☠ TOXIC Instant death — avoid at all costs!

💡 Tips

• Plan your path — cornering yourself is the #1 cause of death.
• Grab ★ STAR before a long eating spree to double your score during the combo chain.
• On Scientist/Cyborg, hug the outer walls — the centre fills with toxic pellets fast.
• The ❄ FREEZE is a lifeline at high speeds — grab it deliberately when you need breathing room.
