Oh, that sucks, unfortunately there's not like a retroactive discount I can give or anything like that, as there's no such features on itch.
As for the UI assets, it's on my list, but yeah i've been busy with work, so i haven't had a lot of time to do any assets for itch at all. There's too much I want to do, but it takes quite a long time and my time is a bit limited recently.
