The concept is fun and it would work well as an arcade game, but it's too repetitive without randomization. Granted, randomizing it wouldn't be easy in 48hrs so that's fine, but still I wish both the blue diamond and white rectangles came from different directions to mix it up... And someone already pointed it out but yeah, you can just sit on the right and do nothing. Also, I see how you tied it to the theme but since the center circle does nothing, I can't really say they are connected, I think it's just a spinning lever.
But hey, not saying it put you down, many people had interpretations that don't quite fit, and that's fine, it was part of the challenge and in the end you came up with a fun concept overall. What I'd do to make it fit the theme better is make the center circle do something, have a function, because then it would feel like a separate entity connected to the smaller circle.
