Hi!
This is a bit of a random thing to complain about (and not a huge problem or anything) but I thought I might as well let you know in case it was an accident, but this is how your preview images display on my devices (apple laptop and apple phone):

^Thumbnail^

^Full screen^

It could potentially be an issue because at a glance the thumbnail doesn’t appear to contain any text, which led to it being ignored at first (by me at least).

That's odd, thanks for telling me. When this was initially posted the thumbnails looked just like the full screen version, but they have the same "corrupted" look on my end now, too. I've tried deleting and re-downloading them, but that doesn't resolve it. 

Whatever the problem is, seems like it's on itch's end. I'll try to contact them about it.
