First of all you might want to change your game since the name leads people to believe it is about something else ans has already been pointed out to you.
Also having large,open rooms with very little in them will drop you fps like a rock.
I have seen people take stock media and make a decent level out if it.I have enen done so myself.
It looks like you just slapped down a few prefabs and put a few models in them.
Speaking of fps drop the outdoor area looks like it would kill your framerate.
I am not saying this to be mean.I am saying this to be helpful.
Downsize the areas you are using,use more media and try to be imaginative when using media.
And,for heaven's sake,change the name of your game.If you don't you aren't going to get the kind of feedback you want and you are going to offend someone.
Go back to the drawing board and put some effort into it.
Even a decent game is going to require some effort.
