I'm baffled as to why Sonic 4: Episode 2 has WORSE reviews than Episode 1! It fixes a lot of problems, like control and also physics! It's not perfect, but still a lot better!
Nope, you''re always controlling Sonic, and Tails is always following you. He's also still invincible. =P And the controls are better in the way that unlike Ep 1, Sonic doesn't't stop the moment you let go of the control stick. That was annoying. =P
