There is nothing wrong with the website. I would like to see the code go open-source. I think it would be beneficial for developers to learn from this. This is a solid piece of work. Additionally, I would love to contribute to the code base and perhaps fork my own version.
It might not be such a bad idea to open source the game, to be honest. It could allow for more frequent updates (with the help of the community) as well as allowing other developers to build off your code and, for example, port it to other OS/systems (I saw 2 comments already asking for a 3DS file version and an Android app)
