It's not hard to get around, but it could be a little confusing for some because the wording on the itch submission page makes you think you should match the game window size when in fact you need to make it larger. And it isn't clear to me how much larger or how much padding is applied since the frame doesn't wrap the content on its own. Every time I've adjusted it to make it look right I've had to change numbers and refresh the page several times to get it right.
