Thank you for the encouragement.
I am doing my best to post an update in late January or early February.
(As I make the game on my free-time, it's quite difficult for me to estimate an exact publication date).
Unfortunately, I got a bit enthusiastic... I had less free time than I thought in January, and I'm afraid it's going to take me a few more weeks to finish the update.
I'd rather delay the release a little bit, than release a new version that is very technical and with finally not many new CGs.
Sorry for the inconvenience
So, I prefer not to give a precise date, for fear of being wrong again in the evaluation of the time needed.
