Marble Garden Zone

This is a sub-page of Proto:Sonic the Hedgehog 3/Sonic 3 Zones.

To do:
Object & Layout differences

The player doesn't start up in the sky.
The drillbot enemy seen throughout the level does not play any sounds when drilling.
Tails seems to be able to influence the spinning top object when both he and Sonic are on it.
The spinning top object doesn't fall out of the level when hitting a dead end.
The chain with spike ball object plays no sound.
The spinning wheel object makes no sound.
Neither Sonic nor Tails have animations for grabbing pulleys, instead continuing whatever animation they were playing before grabbing on.
- The "switch" sound plays when grabbing the pulley.

There are some misplaced rings in Act 2.
It's possible to see below the level in Act 2.
When the player encounters the Act 2 boss, the background is buggy. The player also dies when they hit the bottom of the screen, so two-player Tails must be used to start the fight properly.
The game lags a lot during the Act 2 boss, and it's possible to stand on the air.
Like with Hydrocity Zone, there's no transition to Carnival Night Zone.
