Matt, I figured it out. It was the highlight color scheme.
I was clicking when the color change occurred, but the color blended into the environment. Because of that, I thought the darker color was the actual selection.
Perhaps a simple alphanumeric selection / input would resolve that issue. A green highlight color for the selected choice could also help distinguish what is currently selected. Even a simple up/down toggle would work.
I made it to the airplane ride and rode that thing for about half an hour. LOL! I stayed on it that long because I was trying to figure out how to land it. LOL! Maybe an “I” key mapped to instructions would help, or an Instructions button in the Pause menu.
Boss, it is a fun and engaging game. I was entertained, very much so! Solid!
