Objects

Description | |
---|---|
The ? monitor, destined for 2P versus mode can be placed, and when broken, Sonic will transform into Super Sonic. | |
The prototype Star Post seen in earlier versions of the game still exists. When deactivated, it is yellow, rapidly flashing white and red once Sonic has passed by. | |
The diagonal lifts still exist in Metropolis Zone, except unlike earlier prototypes, they do not move. | |
Slicer with a blue palette can be placed in Metropolis Zone. | |
Stegway with an incorrect palette can be placed in Hidden Palace Zone. | |
Horizontal versions of the breakable tube-like objects in Oil Ocean exist. They function in the same way as the final game, but send Sonic and Tails left or right rather than up. Once Sonic is travelling, the player can't make him stop unless he collides with an object - even in edit mode the player will continue to travel. | |
Fully functional horizontal and vertical fans exist in Oil Ocean Zone. | |
The auto-rolling object, usually found before tubes to force Sonic and Tails into a ball, can be placed in Casino Night Zone. It is represented in edit mode as four spring icons, which are not used in any version of the game. | |
Bumpers can also be placed in Casino Night Zone. | |
Doors for Chemical Plant Zone, with the correct artwork. | |
Both horizontal and vertical variants of the Spiny enemy for Chemical Plant Zone. | |
Grabber enemy for Chemical Plant Zone. It will release an animal if destroyed, but it doesn't move yet. | |
Unused doors for Aquatic Ruin Zone. They're unused in the final game too, but here they are just solid objects. | |
Chop Chop enemies for Aquatic Ruin Zone. | |
Whisp enemies for Aquatic Ruin Zone. | |
Grounder enemies for Aquatic Ruin Zone. | |
Bubble object for Aquatic Ruin Zone. | |
"Growing" pillars. | |
Pillars where the bottom drops off when Sonic and Tails run beneath. | |
