I mean, if the tags ("Erotic, Femdom, Monster Girls, Ren'Py, Text based"), the name (based on Monster Girl Quest, which was also an explicit inspiration for the game in general), and the fact that literally every fuckable girl has at least one female dominant sex scene (even Beris, who's explicitly submissive, will take charge and fuck you silly if you annoy her too much, while there are a bunch of characters that simply have no way for you to be dominant) all didn't give it away, there's also the part where the dev openly admits that the game was made because he couldn't find a "soft femdom" monster girl game.
Sure, it leans more into gentle femdom, but you have to ignore most of the content to miss it. It's neat that you found enough interesting stuff in the margins, but the game really isn't subtle about what it's about.
