I played Day 1 and made a TikTok account just to comment assuming you were more active there (I screamed internally from happiness when I found out you're a trigun fan too!)
As a veteran otome game player, a fellow aspiring writer, and a fan of slightly creepy stuff, I greatly enjoyed this VN! In my opinion, it's better than other similar on Itch.io
On the note of writing, if you're need of assistance, I'd be glad to offer my help as an editor. Your writing at times reminded me of mine and I even wrote down a few lines that may be quite useful for my novel. Alan is like a mixture of one of my 2 main characters and the upcoming antagonist so your VN was entertaining on that front too :D
