blue food scores +10, grows your snake and resets your 10-second timer ✅
red food scores -10, shrinks your snake and doesn't reset the timer ❌
The catch: every second, the two foods swap places — so the food your snake is rushing towards might not be what you think it is by the time you reach it.
You must eat at least one blue food before your 10-second timer runs out, or ➜ game over.
Every time a food is eaten, a new obstacle and a new pair of foods appear.
Hold the arrow (key or on-screen button) for the direction you're already heading ➜ 4× speed boost 🚀
Hit the edge of the board ➜ your snake bounces back the way it came.
