Congratulations! I played the game several times over and it's really good to see a typical ren'ai story with that typical (classic) plot - in the good sense. No troubled protagonist, no deaths, it's just the thing for the start of summer.
The character art worked well with the BGs, even the combination of drawn and photograph BGs was working - and it doesn't happen often. I guess the whole thing has that light summer school atmosphere all throughout the scenes, and it goes hand in hand with the fact that everything fits so nicely.
The story is also just right - anything more and it would be too complicated, anything less and it would be lacking - I can imagine what the endings that I haven't gotten will be like and that's a good thing.
The music was interesting, almost indistinguishable from the usual bishoujo game tunes, with all their backgrounds and compositions, less emphasis on direct melody and more of the ambient effect, that was really nice.
I was quite happy and content with the non-special Ending 1, because that's what I actually played to reach, I wanted to teach them, not really fall in love with the girls on my first playthrough.
Embarrassingly, I wasn't able to get ANY OTHER endings! Well, apart from that baka one which I tried just to make sure it's not a positive option... but other than that, I was completely incapable
It doesn't matter though, I'll have more playthroughs and more time to play - but I enjoyed being myself, so actually I don't feel bad having ended up with the neutral ending.
It's true that the font is somewhat strange, but personally I don't care about that, and actually it has a nice "onscripter" feel to it ^_^. And so the biggest problem for me is, just like with Elven Relations, the perspective of the backgrounds. I'm really sensitive to it, but then, it seems that many people aren't bothered, so it's not that a big deal generally. For me, it takes a lot of time getting used to and breaks the atmosphere a lot, especially when it is as significant as in this VN - the kitchen BG for instance, but to be honest, except for the blackboard, it's every background that has a perspective problem. Of course, on the positive side, this gives it a sense of strange consistency, so it doesn't stand out, that's why I can live with it much better.
So thanks for this nice game, and if you won't mind, I'd mirror it on the Ren'Ai Archives. And congratulations once again. I have to play some more to get at least one new ending. Replayability...
