We've kept coding freeprince and it is now in an advanced stage, but not in an alpha state yet. Because this is not my only project and I didn't have time (I have to finish the university too) for the last two month, the coding times are much slower than expected. This means there will be delays in the release.
In the last two month we only improved the portability (also worked in IRIX), fixed a few bugs and commented a bit more the code.
As the project has existed for more than a year, I can say it was very productive, the coding was good and the engine is very customizable. I like how the things are going and I want to code and finish my part. I think the balance is positive.
