I sent an email to itch.io support last September, and have had no response. I have sent a couple follow-up emails, but nobody seems to be listening. I don't know if I've done something wrong, and if so, I have no way to fix it. I and my team are really frustrated by this. I was told to contact the email address, not the forums, but in retrospect, it's the only place anyone responded to me: https://itch.io/t/963784/need-help-with-file-limit-for-html-games#post-1975922
I don't like being impatient, but by now, I think I've waited more than long enough.
