Hello Melancholy Marionette!
I'm three routes into SR, and I just wanted to say: thank you.
I play a lot of story-driven games, be it mystery or drama or romance, free or commercial, big or small budgets... A handful of times, I've come across titles made by small dev teams or dev persons trying their best to tell new, surprising stories in spite of the limited resources they had. Those particular games are few and far between, but they have always had a special place in my heart as a player, and they end up staying with me for years. So I was pretty excited when I came across your profile and read the description for this one. And it doesn't disappoint! <3
It's super obvious that a lot of love went into it. I really appreciate you going the extra mile and having an OP (which is super catchy, by the way, I've been singing it for several days). As I appreciate you wanting to include as many CG as you possibly could - I do agree with some of the other commenters, though, CGs aren't the most important feature in an otome. Plus, you can always add more later down the line should you want to and have more funds to dedicate to them. ^^
To me, the main point of interest is the story. And while it's not always perfect (the student route could've been more developed, for example, imho), I'm loving what you're doing so far. You have a pretty interesting concept to begin with, and you're using it in really clever ways -- I just can't wait to learn more about the bigger picture, but all the while, I never want to be done with this game, I'm too emotionally invested not to be sad when it's over. Finishing each route feels really bittersweet, which might be done on purpose?
And Kuro is... fascinating. I don't normally care for yanderes; in fact, I normally hate the trope, but the idea of a constant, invisible companion who's been with you since the very beginning of your life is really interesting. Such a relationship would be both desirable in a way, and a recipe for disaster. So, I find myself excusing a lot of things coming from him that I wouldn't if they came from garden-variety yandere characters (That, or it's just the fact that you write him so well and give him depth and layers, and that his VA is doing an amazing job). Either way, I'm weak for him, even at times when I really shouldn't...
So thank you for creating him. Thank you for making this game, for all the feelings and thoughts it spawned, and in advance for the other three routes (Detective/Gamer/???) which I'm sure will be a trip. Thank you for having the guts to carry the development process through to the end, which might not always have been easy.
I love SR to bits already, and I'm glad it exists. And I'll definitely make sure to check your other works if I ever get back onto a PC. Hope you'll keep on being creative, and stay safe!
(PS: true story: I played Nintendogs as a tween; my first dog was a Shiba Inu I called 'Kuro'. So all the lines about him being a pet/a dog hit really weirdly. I think it says much about the strength of your character writing that I managed to overlook this and feel for this Kuro as intensely as I do. :D)
(Edited for clarity and to correct a couple of mistakes, because I'm not a native English speaker and wrote this at 3 A.M., still reeling from the end of the Princess route. Apologies if this comment is too long or confusing in any way ^^;)
