If you look for one of his replies to an earlier comment, you'll find a link to his patreon post about his next game, Eternum. You'll probably have to look for a few minutes though.
Also, are you planning to add more sounds and effects for the H-scenes in the future? There are so many without any sound whatsoever, not even some naughty music. It would make your game even better, if that's even possible.
Yes, I wanted to know about this, too. I hope that the 0.10 update will be a small file that people with 0.9 only need to add to the existing folder in their PC.
