Sonic the Hedgehog - Electro Block

A fan game that you can play as Sonic, Tails, Knuckles, or Mighty. For some reason, like Sonic Time Twisted, Sonic is the only one that can go Super Sonic by 7 Chaos Emeralds as if taking the rules from Sonic Time Twisted. Sonic Robo Blast 2 was like that until 2.2.X for Metal Sonic and 2.2.6 for Super Knuckles.
