Haah! Did 4 endings so far - solo, amends, single-minded and boyfriends, and this is SO AWESOME! It really met all of my expectations! I'll do a little break now, and then try all of the other endings, as I assume they include the dad and the Lady, and I wanted to draw a separation.
Your art is as great as always, and I definitely really enjoy your adult scenes (I'm pretty picky about the writing and illustrations of that kind of stuff). The only thing that bothered me were the evening talks with the dad. I mean, nothing wrong with that per se - it was interesting. But the fact some of them may repeat in a single playthrough bothers me. I mean, that's not such a big deal, but if I'm to nitpick, it would be that!
And with that being said...
---------------------- SPOILERS AHEAD!!!-----------------------
Your writing is so great I don't even hnnn!!! What I'm going about here is that I'm very - and I mean VERY - picky about polyamorous relationships, even more in games than in series or whatever. It takes a lot for me to like one, and even more to think it's the logical and/or best outcome for the characters. And you succeeded at it soooo well. Since the very beginning I was convinced it was the best way (that's why I tried to avoid it on my first playthroughs, in order to save the best for last - well, the last for now, since now I'll have to do work-focused playthroughs). I really love the way the relationship progresses between the characters and how it doesn't feel "right" for them if one of them is left out. The boyfriends ending is the cutest thing ever, and it's so nice to see such a harmonious relationship.
Now, I must say that I really loved the single-minded ending too, though (did it on Burdoc's side). It's really great (and awful XD) to see how things go crashing down from the half point on, if you don't start to take care of the other character. I find Tomai's reactions very interesting, in that he really doesn't see what's wrong, and makes mistake after mistake without even meaning bad. Of course the ending is awfully heartbreaking and sad, but it doesn't mean it's badly written - it's the opposite! I like the classical otome/BL game formula, but it's nice to see you "stood your ground" with the characters and their relationship. All too often games like that make it "normal" to entirely neglect one or more of your friends to hang out with the one you want to romance only. As I said, I have nothing against that formula as well, it's "only a game", but it's really nice to see a game that actually punishes you for being kind of a jerk haha XD
And one more thing - I love your way of making use of dreams in your stories in order to drop all sort of hints. I love it in Space School, I love it in Tomai, and I'm never bored of it! (speaking of wich, I think I won't be able to resist much longer and soon I'll dive into the current Space School chapter haha)
Aaand I went on for ages, as usual... oh well... XD
