it's all in the title of this post really, if i made it rooms that would be simmilar so much they would look like one room, would that count? (i guess not, right?)

So when it comes to the theme usage i always say that as long as you could make an argument for using the theme in your game then everything is good.  Im always down with people taking the theme in whatever direction that they want.  Also, I'd rather people make the game they want vs making something that fits better in the theme. I hope that answers your question.
