What business in specific are you regarding? And why you shouldn't have a right to say anything about this game (there are public/free and Patreon/paid versions)? If we abide by what you are saying, no one should be allowed to express their opinions, due to it being someone's work, even you since you are talking about his/her work and taking for granted what you are entailed to touch upon and dictating matters on your own. Going forward with that same logic on different matters, would conclude on nothing being reviewed or discussed, since if you are not expressly allowed by the author you can't talk about his/her work (work, homework, thesis, music, games and anything else for that matter wouldn't be discussed), and by proxy, this discussion thread shouldn't even exist.
