Thanks for playing, glad you enjoyed it! I think that idea of spreading the different wheels out more naturally would add a lot to the feel of the game.
As for getting the background a little blurry, that was just a post processing effect. I noticed that for your game, you also used Unity. In Unity, that post processing effect is called 'Depth Of Field'. (I used the Built-In-Render-Pipeline, so it might have a different name for you?) I really have no clue how the effect works, but if you just mess around with the sliders, you'll get something that works.
