Aw, that sounds like a dream team and it shows! Honestly, I think you all did amazing :3
Well, I noticed about the loading time and the subtitles but they weren't a big issue, I just mentioned it in case the feedback was helpful ^^
Buy really, The VA did a really good job and I could understand everything very clearly even if I'm not englihs native :) I do think that you are right and it would be nice to give that choice in the future as accesibility is always a good thing to think of, but in the end we do as we can in the time we have and you really did a lot already!
