First off, it's very small. Because it's made entirely (almost) out of stonebrick, it's very easy to make everything angry-proof. We'd recommend (strongly) that you'd create maps with flammable material on calm, like wool or wood, so these natural houses aren't pre-generated making the map easy to survive. That being said, it looks like it took you approximately an hour to create this. There's not much to it, in terms of play-ability, if you consider how small / restricted this is. I'm honestly not too sure this would do well for RoF. Perhaps if the map was around 90x90 with around a 40 block height? Something more detailed than blocks of redstone, stonebrick, doors, minecart rails, redstone lamps, signs, and adminium.
There are no trees/wood/stone to mine for resources to build with, which makes playing on this map for a first-time player very difficult to survive without any help from more experienced users. :s
