I am happy to announce that there has been some progress in the freeserf project lately. I have had a little time to add some features, and a contributor (wdigger) has added sounds effects and music playback using the media in the data file, and is working on further improvements. In addition, there might be some work done on an Android port, but it is not certain yet if this will work out currently.
Any problems or bugs can be reported preferably on github, or alternatively, in the comments. There is also an IRC channel on Freenode named #freeserf where you might be able to encounter someone working on the project.
