Mushroom Hill Zone

To do: Map comparisons would be a good idea to have here.

• The level layout of both Acts is different, and the differences are very noticeable at the start of Act 1. Knuckles starts at the top of the level with Sonic and Tails starting lower down instead.
• Sonic and Tails just drop down in their standing poses instead of Tails lifting Sonic into the Zone.
• Knuckles does not run into any giant rings at the start of his Act 1.
• The giant ring in Sonic's area in Act 1 does not flash.
• If you enter the aforementioned giant ring without all the Emeralds, you'll be sent to the Hidden Palace chamber with Death Egg Act 2 music playing, then instantly warp to a different Special Stage.
• One bonus room in Act 1 contains a diamond cluster of rings. It was changed to a giant ring later in development.
• Hei Ho's axe can hurt you.

• The lever that Knuckles pulls down repeatedly in Act 2 has a blue handle. In Knuckles' game, the lever doesn't appear at all.
• A giant ring at the start of Sonic's Act 2 (after the Knuckles cutscene) is missing and has a bit of Russian Roulette action in its place. There are two monitors wedged in the ceiling, and one of them is a 1UP monitor while the other is a Robotnik monitor.
• There is no giant ring near the pulley that takes you to the boss in Act 2.
• The Act 2 boss's starting position is shifted to the left slightly from the final. This allows you to score endless hits on the boss without destroying the satellite, and the battle won't start until you hit the satellite itself, thus it was changed in the final so the player cannot do this. These hits also don't count toward defeating the boss.
• The Act 2 boss does not explode when killed until he crashes into the tree, and you must hit him six times after he has zoomed off.
• During the transition to Flying Battery with Sonic and Tails, Tails won't stop running to the right and will kill himself in the pit.
