Collect rings of the same color as the character himself to make the neck as high as possible. If you collect more rings, you will get a better result.
Use arrow keys or WASD to move. Press Space to jump or attack. Stay alive as long as you can.
Long neck is hosted directly on Freaks Games, so it loads without a VPN or browser extension. It works on school Chromebooks, restricted networks, and mobile browsers — just open the page and start playing.
