Sonic Mega Collection Plus Mini

Sonic Mega Collection Plus Mini is a promotional Web Browser game made by SEGA to promote their newly introduced Sonic Mega Collection Plus. Prior to it's name, it is a mini version, instead of having classic games in it, there is only Sonic 1 which is altered a bit. The only playable stage in Green Hill Zone. Sonic Team worked with a user/company by the name thirteen4 to make this game as he/she made the Designing, Art, Program and Sound.

It's more of making a High score game where you run through the level collect as many rings and destroy as many enemies.
