🛑 Polarity Runner 🟦

Switch your polarity. Dodge the hazards. Keep running.

Polarity Runner is a fast-paced 2D platform runner built with Unity. Run through a procedurally assembled world, collect coins, avoid dangerous obstacles, and switch between Red and Blue polarity to survive.

Every hazard has a rule — and choosing the right polarity at the right moment is the key to making it to the finish.

🎮 How to Play

Your character can switch between Red and Blue polarity.

🔴 Red Hazards
Dangerous while you are Red.

🔵 Blue Hazards
Dangerous while you are Blue.

⚪ Default Hazards
Dangerous regardless of your polarity.

Move, jump, and change polarity quickly to avoid incoming hazards and keep your run alive.

🏃 Three Stages

The run is divided into three increasingly difficult stages:

Stage	Distance	Difficulty
Stage 1	0–60 m	Longer color sections
Stage 2	60–120 m	Faster color changes
Stage 3	120–180 m	Fastest color changes

🏆 Reach 180 metres to complete the entire run.

🪙 Collect Coins & Revive

Collect coins as you run and use them to revive after getting knocked out.

Revival	Cost
First Revival	15 coins
Second Revival	30 coins
Third Revival and later	60 coins

Your coins are saved between sessions.

If you don't have enough coins for a revival, you'll need to Restart the Run.

⚠️ Restarting a run resets your saved coin balance to zero.
