Sonic the Hedgehog 2/Mystic Cave Zone
Ok, this is an ok level if you play your cards carefully... Watch out for long spiky bricks if you jump they wont hits you. The only badnik you should be worried about is this bug who turns yellow and you can't be hit when it is.
Same as Act 1 except boss
He's easy all you have to do is dodge spike-like rubble and hit him 8 times..... pretty easy
