The cover looks beautiful, I really enjoyed the switching POVs. I was really sad at the beginning when they died. I didn't notice any grammar mistakes. The world-building is impeccable. I really hope Kaede and Yui get together, but I also really ship Luna and Ellen so harem maybe??? I dunno, I guess I'll have to wait and see.

Its a good story with an interesting perspective. Its very well done and the characters are special in their own ways. There aren't any glaring grammatical errors (or I'm filtering them out). The world-building is smooth because the whole idea is that she gets to build the world.

I imagine the author means % chance of dodging an attack. Or put simply, if you have really high Agility, then it is really hard to hit you.

unfortunate, you have my condolences
