I'd like to point out that this is the iPhone version because I'm too goddamned impatient to wait for any better release. Besides, I'm not focusing too much on the controls anyway.
First of all, let's start with Sonic 4's wonderful innovations.
This is Casino Street Zone. Obviously the most unique level in the game. Not modeled after any other level, no siree this is 100% original bullshit we have here.
The music is nothing short of amazing. Listen to this shit:

Golden. Greatest ingame music to ever exist.
Design? Only the best to ever exist. Sure you hold right alot and the game pretty much directs your movement at all times leaving you hardly any freewill but it looks so damn cool while it does it. It's like "Shit we know you're bored but look at all this shiny shit isn't this game awesome" and obviously it is if you haven't caught on by now.
Buy this shit because even though it's ugly and a ripoff of Sonic 2 and the music sucks and the design is practically nonexistant it's Sonic 4 *crag*ers therefore it's worth it.

Only the Greatest Game Ever.
