Finished this game over the course of a few days. It's not too long and the story is mostly pretty good, fairly realistic and fun without getting too lengthy, too ambitious, or too dull. The mechanism of exploration is an alright way of breaking up the text but more could have been done with it, and a lot of locations are barely used. The framing devices also turn out to be unnecessary, and when you reach the final story (Arisa's), they do away with it completely.
I liked the girls and the idea of doing 2 stories each, but the practucal result was that story 1 was the lengthy/story one while story 2 was the one frontloaded with all the good sex scenes. Sex scenes are mostly vanilla and not anything too great, art is very average.
Of them all, the loli and Arisa's were my favourite, with the tsundere greenhaired girls stories seeming the most rushed.
Overall this is a decent enough VN, very average. It doesn't do anything particularly well but it also doesnt do anything badly either. Worthwhile as a one-and-done playthrough, not something id ever replay.
