From the demo alone this one is promising, the writing is very relaxed and fits the art style amazingly, although I did find a few errors (which I'll describe at the end) it is overall a very nice experience, with a gallery being very welcome.
But about those errors, with the game being available in both english and french, I believe it is within the code what string to be called in which language, maybe depending of a switch that tells what language was selected, my point with this is that during certain points during the playthrough the language kept switching back into french, even though I was playing in english, it happened every time when the message about increase of affection appeared, it was in french and I could only vaguely understand what it was, there are other points like this but it is good to keep an eye out for such
