– It’s the Flash-based version of the classic game! In this legendary side-scrolling adventure you take control of Sonic the Hedgehog. Run through the landscape and collect rings as you progress through the game. Levels will get harder as you pursue the nefarious Dr. Robotnik through forests and even space! Rescue the animals that have been transformed by the evil technology and bring peace and serenity back to your world! But be careful- if you get hit and you don’t have any rings that’ll be the end of the game for you. Make sure you avoid obstacles if you can, especially the game-ending spikes!
