It's a good CG collector, but a dreadful game.
There's not too much to say about this one. The story is your generic Lewd Mark causing our already horny priestess to become wildly easy to corrupt, and a journey that takes you from town-to-town with molesters, con artists, shotas, and monsters that WILL violate her.
The erotic audio is stellar. The VA who did the moans fucking killed it. Her deep, heavy moans actually sound like someone who just came hard enough to see stars. Personally, I hate the fake, high-pitched whining/squealing you always hear in JAV & western porn/other games because it reminds me of how "produced" it is. In contrast, this really sounds like someone feeling good enough to get addicted to having sex.
Praise over. The combat is an absolute pain in the ass. Resource management is painful, and all enemies (even the fucking CRABS) do fuck loads of damage. It's unapologetically stock RPG maker combat. They didn't even try to spice it up. There's some combat H, but it's repetitive and mediocre, especially compared to the event scenes on defeat and in towns.
Unfortunately, the corruption is lightning fast. There's basically no real discernable change over time, except in the way she gets groped, whether or not she'll automatically accept certain harassment scenes, and what you're able to get her to wear.
It's a shame that they didn't gate the heavier lewd scenes a little more, as it quickly dampens the impact of them. Because there aren't any milestone-esque lewd scenes, you never really get the feeling that she's actually trying to resist. It barely feels like a token effort at times. Plus, it kills the vibe a bit, when you're getting to later areas in the game, but they can't up the ante of the scenes because she was already getting fucked left and right by the 1 hour mark.
In some of the scenes, I found myself thinking things like: "How are you complaining about getting railed by this guy, when you willingly fucked 5 random strangers walking down the street just a few seconds ago?"
TL;DR: Basically, if you really like the art, you're fine with corruption that happens in the blink of an eye, and you don't mind generic RPG maker combat, you'll enjoy this one, probably. It's aight, but it could have been so much better.
