Wow I wasn't expecting feedback, but I really appreciate it so thank you much!!
I get what you mean about the backgrounds. I'll have more flexibility when it comes to changing backgrounds as the story progresses... at least that's what I'm hoping.
The character portraits are actually going to stay black and white for a majority of the VN. I know it sounds like a lazy excuse me on my end, but there's a story reason why they are uncolored, and there will be a point in the story where they will have color lol.
I can see why you think the bad end is uninspired, but hopefully you can see it in a new light once more of the story comes out, as the rest of the story heavily draws from the bad end.
I'm also amazed so many people who've read this like the toe ending this was a mistake.
