Ultimate Flash Sonic
This is the best Sonic flash game there is hands down. There are multiple characters to pick from when you start a new game (some of which need to be unlocked) and there are many acts and scenes to play. The game is not easy at all but it offers you the best recreation of Sonic the Hedgehog for Sega even though it's not actually an official Sonic title. If you enter the password given below, you can choose from 5 cheats on the main menu including Sonic-Run 2, Tails Follow, Behind, Big-Cheese, and Moon. I'll let you discover what each one actually does.
