Thanks for the feedback. I lightened the color of the bottom bar. And there were definitely issues with the objective changing randomly. I couldn't quite figure out what I wanted to do with that mechanic. I've now added a 2 second countdown timer to the lower right corner of the screen, that will pop up and let you know the target is about to change. It can take anywhere from 3 to 9 seconds for the target to switch, but the game will only show a warning for the last 2 seconds.
