Completed 5/7 worlds. This is ridiculously easy compared to its predecessors, holding the stick to the right results in Sonic-based awesomeness. Not much to it. The worlds are crazy, but feel a bit empty. The japanese soundtrack, however, is fantastic; crazy hardcore rave music with random samples, orchestra hits, breakbeats. The music is composed by Naofumi Hataya, known from Golden Axe II, and Masafumi Ogata.
Completed 6/7 worlds.
Completed Metallic Madness Zone 2 - really, really confusing and poorly designed level. So many needless red herrings and no rhyme nor reason.
So many random deaths in Metallic Madness Zone 3!
completed the game with Sonic the Hedgehog.
I got the bad ending, because I completely ignored all the time stuff...
