Unity - Completed - Newona, Ritual Offering to The Depraved God ~ The Surrender of the Transforming Gender-bent TS Exorcist Girl [v1.03] [I'm moralist]

It's not great.

It's a deckbuilding game first and foremost; the pornographic scenes are either at the very start when you spy on some characters (that immediately disappear from the game) or as a "punishment" for using get-out-of-jail super moves. The scenes? Charming, assuming you're into the whole eldritch monster and tentacles corrupting someone into being too horny to say no anymore. (Charming is probably not a good word for that!) These are surprisingly longwinded, although only have five~ CGs. There are some chibi-animations of your Monster Stand violating your character here and there, but they're brief and textless.

... And that's it.

Some of the cards allude to lewd things, but they're superficial at best. The rest is a creepy pasta horror while you go through a simple awful deckbuilding game; there is a strategy you can use for it, but most of your actions are completely out of your hands. Your deck gets flooded with debuffs as you go on, monster moves frequently add them to your deck, and there's not much of a way to prune them out - sometimes you can use them offensively, but that involves you drawing that card through all the chafe. Oh, and your health is also your deck, so you discard things as you take damage anyway. (And, weirdly, gain health as you get debuffed.) The amount of bad cards combined with the fact your handsize is a tiny four means you end up with a lot of dead turns just clearing out debuffs, only to get given more by the monster you're fighting.

It's all very strange. It does seem to be some sort of prototype for a more involved game, that or they ran out of budget; the backdrop is for a more traditional H-RPG you see on here, but then everything is discarded to just move through a random encounter maze. There's tracked corruption mechanics on the heroine, the idea that she's boinking tons of monsters as you get corruption, but... none of that actually happens.

just play an actual deckbuilding game on steam like slay the spire or phantom rose or something

I'm Moralist's games tend to be a bit divisive. Themes like corruption, rape, body modification and bestiality and/or tentacles tend to be prevalent. Newona is no different in that regard. The art for the CG-scenes is good, so if you're into that sort of porn content you might enjoy this.
The main sex scenes, one of which you'll encounter immediately upon starting a new playthrough, are really wordy and focus mostly on the mentality of Newona as he first is forcibly transformed into a girl and then as she is corrupted, mainly focusing on enslavement/impregnation parts. I think a lot of people might find these sex scenes a bit drawn-out.
Also, the 3D chibi models (for Newona for example) aren't exactly impressive and the monster models on the map and during fights also seem a bit lazy and don't exactly get me aroused.
The main gameplay consists of playing a card game. There are some porn games that do this, and in my experience the card game mechanics tends to distract from the porn. It's no different in Newona. So far I have done one full playthrough (getting a good ending) and a bit of another playthrough, and about 90% of my time was spent during card game matches and between matches modifying the deck/walking between the rooms on the map. What I mean by this is that quite a small amount of your time will actually contain any porn/sex scenes playing this porn game. That's quite a shame. It makes the overall experience feel like a waste of time.
The card games can be quite frustrating unless you're fine with losing repeatedly. If you want to win you have to either grind out some battles for loot (better cards or rarely more card slots and extra mana/play points) or get real lucky if you rush bosses. You can finish the game pretty fast by ignoring as many battles as possible and rushing bosses, but I wouldn't recommend that since then your deck will probably be too weak to beat the bosses.
If you're having trouble you could try cards that discard the opponents cards, cards that heal you, cards that fetch cards from your graveyard, etc. There are some quite powerful cards you may discover but of course most of them are rare.

This gets 2 stars purely for the art and nothing more. It's a terrible game in every last regard. Terrible deck builder, terrible porn game, terrible everything. It plays horribly, punishes you for wanting porn, and then fizzles out entirely if you go for it. Somehow, the final CG is even worse than what you get on the first and second level of corruption. It's just....lame. Everything about this game is lame.

The art is fucking GORGEOUS, but that is bait if ever there was any. The game's 3D element is entirely pointless, just making you run around for no reason other than to be a bit unique, I guess. It adds nothing and I only saw 3 sex animations out of the 60 it claims to have. Kinda weird, given how I went through 2 full levels and did the entire corruption thing.

What is with games punishing players for wanting sex in their FUCKING PORN GAME. It is the most confounding thing to me. You're not selling a story. You're not selling a deck builder. You are selling a porn game with that slapped on. The game's title has tits and a demon blasting for all to see in it. Of course people are here for the porn. So don't give me a game over when I seek it out. That design is fundamentally stupid as fuck.

This is such an upsetting game. The art is so gorgeous. The scenes aren't the best written, but they're not the worst, and they've got length. This has so many traits that should make it shine, but it just ends up being utter trash. Such a waste of my time. It's like mixing a full bag of confectioner's sugar into used motor oil. Once you get past the surface, it's still just waste.
