We're currently not working on the project. We had fun and an update was in the making at the time, but it seems like this project will not receive another update for the foreseeable future. We hope, that you understand that it will most likely remain a prototype.
I personally still start the game from time to time just to enjoy the music created by our talented artist Moritz, who also created the Models.
Some of the mechanics and ideas went into other games that we developed after Rails Ahead. :')
