Demon Deals is a harem game that covers a lot of familiar ground. It's an RPGMaker game starring an unassuming everyman who, through magical means, acquires a comically large penis and must seduce and breed 30 women, including his family members, or his soul is forfeight.
If you're into the festishes on display here, you really cannot do better than Demon Deals (there are several games that hit the exact same marks as DD as well). Where it stands heads and toes above its kin is its presentation. The western cartoony art style, while extremely exaggerated, is incredibly expressive. The fundamentals of cartooning (timing/squash and stretch, etc) are in full swing. There are minor nitpicks you could make about small things (sometimes hands or feet are a little wonky), but it's not really worth bringing up.
Another trait that sets DD apart from its contemporaries is the amount of effort that goes into the worldbuilding, characters, and the conceit of the fetishes. Like, an unprecedented level of effort has gone into covering every reason why the protagonist would be in a situation to seduce his own family. In other games featuring this stuff, you just go with the flow and suspend your disbelief. But here, each little detail ties into making the contrivance feel organic.
For instance (minor spoilers ahead), you end up cuckholding your dad. How? Well, you move into a new place, and your parents are helping you unpack. Turns out your sleepwalking medicine went missing, and your parents go back home to look. During this whole debacle, you enter into a contract with a succubus who demands you breed women in exchange for anatomical enhancements.
A quick inspection around your new place reveals your dumbass dad packed your phone in a box full of textbooks. You borrow a phone to call your mom. She yells at your dad and offers to stay at your place until your medicine can be replaced, to keep an eye on you. Turns out you need to be physically exhausted to not sleepwalk. It's suggested not only exercise, but masturbation, but it turns out you can't orgasm unless it's with a female companion. Your mom doesn't know that, and you tell her that 1) you dont have internet, so no porn 2) you don't know any girls around. So now the pressure is on. In a short time, it establishes the stakes, an external conflict to getting laid, the fact your mom isn't satisfied with your loser father, and why you'd be shacked up with your mom in the first place with next to no options besides pursuing the fetishes this game is delivering on. Efficient and to the point.
So, the conceits are in another class, as is the writing, characterisation, and art. It avoids a lot of go-to tropes and cliches (the sister isn't a bitch and the mom isn't a slut who's about to jump on the protagonists dick with the smallest push). Just seeing the sheer amount of effort here is worth it.
But, it has downsides too. There's a few bugs, sure, but there's also a bit of the grindy factor in certain parts. Getting through a school day is grindy and cannot be averted until you finish it, so you'll be going through repetitive stuff over and over. The combat is an attempt at Action RPG stuff, but the engine is not really built for that, and it's awkward to play and not very fun. Sometimes the interface is clunky and non responsive. You can exit every menu with keyboard strokes but not the map for some reason. The pacing in parts could be better. That, and due to the sheer amount of work the dev puts into it, following this game during production can make it feel like a slowburn.
But these are all minor criticisms. If you're into what Demon Deals has to offer, you will have a blast. Throw the author some bucks over on patreon, to keep em supported. I don't want this game to die.
