Maze Track backgrounds

Ok, I'm looking for suggestions of terrain types of backgrounds that could be put into maze track. This includes none moving objects as they are actually background items with an invisible object that prevents the player moving over it.

Here's a screenshot of the backgrounds I have so far:


Note that backgrounds overlaying other backgrounds are simply on a different tile layer with transparent parts where the object ends. So they're easily added to other backgrounds.

So is everyone content with just those backgrounds?

No one has any suggestions no matter how farfetched.

I'm still getting it clear on what we gotta do.

The whole idea is I make the game builder, all the objects, backgrounds and all that stuff, then I release the builder. You guys use it to build maps, the idea of this thread is to choose terrain types for me to make so you can make the styles of mazes you want. For example, I not only have a cave terrian for...Caves of course, I also have brick walls and carpets and wooden floors for inside houses and grassland of outside or woodland type maps along with trees and bushes for the grassland/woodland type. Then there is beaches and deserts and oceans.



The above map is an example using all the backgrounds currently available.
