Speaking of, since Chaos Emeralds are now implemented, are there multiple endings depending on how many you have? And were other elements implemented, like the scene before it with Sonic releasing the emeralds?
Also was the "Sonic Team Presents" text put back too? I found the unused graphics of the "Somari Team Presents" version, so I'd imagine it's possible.
Also also, there's a bug in Labyrinth with floating platforms. Basically what happens is that when on the platform, Sonic can go through any wall above him while the floating platform continues to rise him up. Sometimes, doing this crashes the game. I think I know why this happens. Usually, in the original Sonic 1, doing this makes Sonic die from being crushed due to wall/ceiling collision. There doesn't seem to be any ceiling collision here; if you walk in any direction, you can't zip like in the original and go to the far opposite direction of what direction you press, you just "fall" through the ceiling. Fall as in "Sonic continuously going upwards while the background/camera freaks out until you reach the actual level map." Is there a way to fix this?
