Sonic 4.2 is actually a great game, when the degree of difficulty was not so high, the controller is not so vague and the bosses not so easy! Apart from these problems makes that game really fun! As such, it has to contend with the same problems as the Android version of Sonic 4.1. So who is frustresistend or thrill seeker should strike necessarily. Someone, however, could spin while any unfair place (like me ;-)), should rather buy the PC or console versions. Because who better control, and could thus evade some traps and enemies better and can respond faster.
