- Back to: Sonic the Hedgehog 3 (prototype; 1993-11-03)/Comparisons.
Act 1
Angel Island is introduced by Sonic riding a (broken) surfboard. There is no Tails, Tornado or Super Sonic. Starting from the level select skips this intro, so the only way to see it would be to let the demo play at the title screen.
The hedgehog abandons his board and meets a very different looking Knuckles. Rather than attack, Knuckles stands around making some gestures then runs off to the right.
Jump ahead of Knuckles and he'll turn blue.
Title cards are not perfect in any Zone in this prototype, but the Angel Island one seems especially bad.
The left hand side of the screen is not locked, meaning the player can backtrack to the beach as soon as they start and promptly die.
Tails flies in when gameplay begins, rather than before. He's also slower to arrive.
This rock can be destroyed by jumping on it. In the final, the player has to push it. There's nothing down here but a spring.
Fire Breath breathes fire in the first encounter. In the final, it just launches missiles.
After Angel Island catches fire, Sonic and Tails are presented with some very different layout changes. There are falling logs to jump on.
Sonic and Tails do not have a dedicated underwater palette when Angel Island catches fire.
During the Fire Breath fight, the fire graphics on the sides of the background trees are corrupted.

Act 2
Tails takes less of a beating from Flying Battery as it drops bombs. This is because unlike the final game, Tails is not pushed forward by the moving camera, so will just be knocked off-screen.
The bug allowing you to jump off the bridge and back onto the ledge as soon as Knuckles hits the switch doesn't work as well here, because if Tails drops off-screen, Hydrocity Zone will begin. In the final, it's only Sonic that matters (unless you're playing as Tails).
