I believe you can use CE to do something about it. Though I wouldn't recommend you to buy more game from these guys. Despite great art works, they are having a very questionable business model where itch.io customer have paid 25USD can end up with less content than steam customer who paid 10USD( Basically just pushing people to buy the same game again and again to make more money). A indie studio with a business model like big greedy corp? That's always not a good sign.
