Don't get me wrong, I didn't mean to completely discourage you or anything. I still liked some of the characters and their backstories, which kept me playing, and I think I finished all (!) of the routes after all. So I'm kinda like those people who 100% clear their plate at a restaurant and still complain about the food having been bad. ;)
Still, let me give you just two (of countless) examples when it comes to spelling, and that's Diane. I liked her route, so I found it a bit irritating that her name header - when she is saying something - would suddenly read "Diene" instead of "Diane". That's a bit much, you know?
Or one time Honoko says "I thought you would be more existed for it", when it's about their continuation of magic practice. Clearly, she meant to say something like "I thought you would be more *excited* about it". "exist" as in "to be present in this world" doesn't fit here at all.
See what I mean? And it's literally full of that, you'll get it every few lines. Had to play only for seconds to come up with those two mistakes just now.
However, if you do make another Yuri VN, I'll surely be back on board again, because I wanna see how you'll continue from here on out (and because I simply love Yuri). And I may critize again as well... Not sure if that's encouragement or a threat to you though, haha... ;)
