Made worse in that it's only the second zone in the game. Chemical Plant Act 2 and the damned bottomless pits, crushy things, and Mega Mack.In time attack mode you'll still die, but the spikes are removed so it is just a simple bottomless pit. This seems to have been noticed: in the official IOS remake, two changes were made to it: in the main game, the spikes are gone and you warp to Hidden Palace Zone instead of die.It doesn't help that this level has several dangerous Badniks of this. Instead of being bottomless, an unnecessary row of spikes means that if you're Super Sonic, you have to wait until you run out of rings to die. Mystic Cave Zone and the notorious spike pit.The boss fight is very long and difficult, too. It also features 3 dangerous Badniks that can attack the player very easily when not paying attention. To make it worse, every other Zone in the game has 2 acts, but Metropolis Zone has three to make the suffering longer note (in reality, this is because the game was supposed to have an extra Zone which was cut, and thus the nearly completed act was included in Metropolis Zone). Metropolis Zone, not only because the stages are massive.There the air bubbles are so far and few in between that the countdown music is practically GUARANTEED to start haunting you, and if that weren't enough, the air bubbles actually take much LONGER to spawn than the ones found in Labyrinth Zone. Scrap Brain Zone Act 3 (if you don't use the shortcut, anyway), especially if the player falls into the deepest part of the act.Even Sonic Team thought that was too harsh! It could've been worse - the original level order was to have Labyrinth Zone right after Green Hill. Despite there's no "real" boss battle in the Labyrinth Zone, there are traps strewn about, wasting Sonic's time as he deals with rising water and not a ring in sight. The maze-like designs in both Acts 2 and 3 certainly seals this level's fate for this trope. As pictured above, the Labyrinth Zone earned infamy for its steep Difficulty Spike, a strict Oxygen Meter (that after twenty seconds of not swallowing an air bubble, Sonic drowns but not before the player has to endure the dreaded countdown music) and for having traps that Sonic hasn't seen yet.Still not as bad as Labyrinth or Scrap Brain Zone, but it is earlier in the game. wait, no, between the tricky-to-time pounding things, the lava chase, the surprise flames during the lava block rides, and the fragglemuffin' Caterkillers, it actually is kind of hard. It's not "difficult" so much as "annoying".

Not only is it full of traps and tough obstacles, but it comes right after Green Hill Zone, which is much faster paced compared to this one. The Marble Zone can be hard to some players.
