Sorry, didn't mean to oversell it. No new modes or anything like that. Just camera bugfix, saving the sound settings, and a few extra levels of changes for fan service. I should be able to finish it around the end of the month.
Sorry to disappoint, but probably not. I'm pretty happy how this one turned out and am working on my next game. So I'll fix bugs, but probably not make any content updates.
Not at the moment, I've thought about doing a production blog or something like that, but my work is really sporadic, so I'm not sure it would be very interesting.
