I just wanted to let anyone who doesn't know that there is an english translation in the works for Denpaningen No RPG Free on github. I don't know how long it'll take for the developers to finish, nor how much progress they made, but there is one in the works. Here is the link for anyone who wants to play the english patch "demo." Here are two links, one that is the translation project, and the other is the script that is used to help with the translation project.
