I don't exactly recall how I found this VN, but I've had it on a to-read list for a few months, and now having read through the current build, I can confidently say that this story is FANTASTIC! I had high hopes, but after actually reading it, you have exceeded my expectations! I am thrilled for the next build, especially after that ending. I'm vehemently looking forward to seeing how the situation between Kai and Eco proceeds, especially with Eco having to admit the truth of his visions to Kai (or at least, I assume he will).
I saw your reply on another comment say we should expect it this month or next month, but even if I have to wait longer, I will definitely keep an eye out for build 3.
