What did they add to 3?

From what I noticed:
-Tails and Knuckles both have intro cutscenes now
-Super/Hyper forms require you to press a different button to activate. This allows you to jump and use shield abilities without accidentally activating your Super form.
-Big Arm is back in Launch Base Zone for Sonic and Tails in Sonic 3, and when you beat him, they reimplimented a previously unused sprite of Eggman going back to the Death Egg as it's falling. Then it cuts to the title animation of Sonic & Knuckles before Mushroom Hill Zone starts.
-The out of place Eggman sprite in Flying Battery Zone Act 2 for Knuckles has been fixed. Now it has Egg Robo in it like every other boss in Knuckles's playthrough.
-The laser boss in Flying Battery Zone Act 2 can be defeated by hitting the blue light (just like in Sonic 2). Previously, you had to wait for it to shoot all its lasers out and destroy itself before you could move on.
-Sonic's sprites are much better animated when rotating, and Super/Hyper Sonic has new sprites to fill in all the missing ones from various animations, as well as new Super music that isn't ear-grating like the original lol
-New credits music at the end
-Knuckles has animation to his sprite when he's gliding
-They changed the music for Carnival Night, Ice Cap, and Launch Base due to copyright with Brad Buxor/Michael Jackson. They're from the Sonic 3 Prototype, but are inferior to the original tracks imo
-Certain cutscenes now take control away while they play out to prevent glitching (ie: Angel Island Act 2 with Knuckles destroying the bridge)
-idk if this was in the original, but if you have a bubble shield and you run into an air bubble, you don't stop everything and breath it in.

I mostly like all the changes imo >_>
