Mostly replying here just to make sure you get a notification: I’ve posted a response to Unpainted Productions that might clear things up for you too. Also, I love the look of your game so far! The key/buttons/etc. are absolutely no problem: they’re obviously drawn from the Crayon and Kazoo pack. In fact, if there’s any chance you’d be willing to share them with others, I’m now collecting submissions for a community expansion.
