Very very cute, And the endings aren't too hard to get. Art is fantastic, Humor got a few nose exhales from me, Foxy (I named them Audrey in my playthrough) is incredibly endearing, and the "plot twist" of Melo having her on payroll simply to get people to shut up makes so much sense and makes the "Tail between your legs" ending that much more sad. Repeating the same thing with little to no variation is a bit annoying but the game is very short so it doesn't affect my rating.
Rock paper scissors, memory, and a "rhythm* game are more harmless than aggravating. They are just fine, not good, not bad. A little slow on memory and rhythm, but ultimately dull. (Though that last minigame can be especially lopsided, Sometimes the circles move too fast, or they are too close to the center already to properly react, and the gradual decay on the bar just make it last longer than it needs to.)
I don't know enough about mythology to tell who Melo is supposed to be, Melo makes me think of Meliodas, but his initials of M.N. Pandemonium make me think that wasn't the intention. My only complaint is that there is no gallery to look at all the cute character art.
The name Foxy Succubus maker implies a level of customization that it doesn't have, a more appropriate name would be "Foxy Succubus Trainer"
Still, very cute and is exactly what it wants to be which is a irreverent visual novel about a shapeshifting fox demon trying to be a succubus. Love it, and all my complaints don't take away from my enjoyment.
You're hilarious, definitely coming back for future updates!
