Doesn't make much of a difference to us! Steam's cut is higher than itch's, but on itch we pay more processing/transaction fees, so it kind of evens out. The good thing about itch is that people can pay whatever they want, so if the Steam price is too steep for them they can choose to pay less, or if they want to tip us a little extra, they can do that too. But as far as we're concerned, we're good (and grateful) either way 🙂
