(The game it's in a W.I.P state: https://scratch.mit.edu/projects/755297517/) Just press the green flag to start to see the second cutscene press space or click/tap on it. this is not a game btw if you want to watch the intro again just press the flag again if you want to watch the ingame cutscene concept just press or tap on the title/project.
I just got bored and made this. I had an idea of making a Sonic fangame in my head for over a week now, so I made this. I used the Sega intro sound, part of the sonic 3 intro and prototype knuckles theme
