I would help, but I don't know much about Unity. It's all about the journey, you will get much better as time goes on. I can't tell you how many abominations I have made (not to say yours is, it is most defiantly not) that make this look like a triple A title with 10 years in development..
Like I said , its a solid game and I can see a ton of potential it as you expand upon it.
