Nice job for a first try.
I like the overall look-and-feel of the hand-drawn game, clearly designed and written from the hip, with teenage spontaneity nonseriosuness, rolling smoothly into rose-petal romance which is very rarely seen on NG, even in dating sims. I think "Hentai Sim Girl" which long held the top spot was the last one which was at times actually romantic.
However, some criticism: the game has a very linear, no-surpirses, riding-the-rails feel to it. Needs more complexities. Also, the dialog was at times cheesy, though maybe that was tongue-in-cheek, but at any rate I did not like. Also, I never approve of G-rated dating sims because dating is not G-rated. Sometimes people get squeamish about it, but the truth is love eventually gets physical, at least to some degree, no matter which sex you are... try falling in love, see what happens! A love game with no nudity or sex is like a mystery novel with no murder or an action movie with no fighting.
