Very good start, renders are nice, characters are likeable and cute, you have choice how you treat your love interest (so far seems like love vs submission). The story so far is not complicated but have some potential but... most importantly... the game have that "thing" that make you care about characters... and it's isekai - still not very popular VN theme.
Another good thing is that previous dev game had very regular and substantial updates.
So yea, really worth trying imho.
