Thanks for the feedback! Yeah I realize now I needed to flush out and communicate the story better. So the game is supposed to be a collection of memories from your childhood, going to the Arcade.
From the start you think you are just at an arcade playing games. Then the second game ends at a prize counter with the prize slowly forming. Finally the third game is just a full flashback, a guardian, older brother, or older friend is taking you to play games. But once you get to one of them they disappear and the veil is dropped. You are alone in the old arcade. The prize on the table at the end is the memories you regained.
Maybe some other patrons at the arcade that also disappear and then a cutscene to help explain what happened would have helped.
