Sonic Before the Sequel Aftermath 100% Walkthrough

This game set the middle Sonic Before the Sequel storyline. Link: https://gamejolt.com/games/SFGC/491376 The reason why I didn't play "Sonic Before the Sequel Aftermath DX" is that this game (even in third-party links) is not available as if it no longer game exists it but the videos still exist for while.
