So, I am working on a VERY simple encryption for the maps for the BlockBall game I'm working on, and I could use some people who think they can decrypt it to tell me how secure it is. Here is a small sample of part of what an encrypted map looks like. If you can decrypt it, please post what you think the answer is here so I know whether or not to beef up security. Bare in mind, this is a VERY simple encryption, I don't expect this to be undecrpytible.

Again, this is not going to be impossible, I just want to see if it is TOO easy. Enjoy.
