I'm glad you like it. Yes, I am currently working on an artbook which will include a walkthrough as well as many other things.
I aim to release it in either September or October.
Oh really? Awesome! 😊 Meanwhile, may I ask you if there's a happy and romantic ending with Haru? Because I'm trying to reach it, but maybe I'm doing it for nothing xD
Haha, yeah Haru has a few routes. There are two good endings for Haru, but the way to get to them only involves making two very specific choices. I won't tell you which ones though since that would ruin the fun =) good luck!
