unironically 5/5 in all categories.
At first I was just thinking about how much I liked the genuineness of the aromantic/asexual representation, as someone who has been through similar situations to Kotohime's from part 1 and the early part of part 2. But, by the end, I had to take several breaks in my stream because I just couldn't stop crying. This hurt really bad. In a good way.
It's, shocking, that you say this was your first time writing something over fifteen minutes. Though, I do very much understand the situation of writing a lot without ever really showing anyone a completed work. But this, you say you tried to make it emotionally resonant, well, the 40ish people who were in my stream at the end of it all certainly seemed like none of them could stop crying either. It, ah, it was a lot, and I really think that you succeeded in all fronts. Even the little danmaku minigame had some really fun patterns to try to dodge, even tho dodging them wasn't really necessary.
I can definitely see why you needed extra time. But to me, this was far and away the strongest entry in any of the Touhou game jams I've played through, and I feel you succeeded on all fronts. I hope that you feel encouraged to write more for public consumption.
