Alright, at first when I saw someone comparing this to VH I had my doubts, even gave up on playing it the first time. I was under the impression that this was some sort of cosmetic clothing and monster rape only game, after a while I decide to try again, and oh boy was I glad to be wrong.
IMHO, this is the game closest to be a true loyal VH-alike (not exactly a successor), and may I say, in some regards even better than VH, it managed to be pretty polished, considerably high quality, and even great drawing design. This level of quality is even very rarely achieved by most commercial games, let alone one that tried to have this sort of scope, man just look at those lighting shadows, that smooth animation, floating dialog and whatnot, this guy really pushed WolfRPG to its limits, a decent dev finally.
Pro/Con Review:
Why did I say it's a VH-alike game? Well the rogue action-rpg is the obvious part, add to that the battle rape, the lewd stat tracking, free roaming, day/night time tracking, eating/peeing. That's some obvious influences right there, and I would even wouldn't doubt if this guy was among the devs that tried to implement this stuff in VH originally. But there is a major difference, all of these features have been decently implemented and polished, all of these things work and serve a purpose (sort of), and are reasonably balanced (like meals for bar recovery). On the other hand, one of the things that didn't have a purpose, is the pissing mechanic, which I guess could be some sort of squirting while orgasming. Another thing which is pointless, is there virginity keeper, which is nice, but apparently serves no purpose.
The game is (sort of) quest focused, you go through areas and dungeons to unlock new places, and after that you can just quick travel all around. The game is also very light on dialog, though it feels the author kind of skimped on the translation, making it more of a shell with only the essential information. For that reason, initially it felt that I was just hitting random events, quest tracking is very hard and sometimes, even when there were some hints, I didn't know where I should be going to. Still I was quite surprised, that I expected something really shallow, but instead end up with a big open world and multiple different quest lines. For this reason as well, maybe a quest tracking, or adventures guild system like in VH, could be a huge improvement.
Furthermore, the battle rape system, I hate GOR and initially it feels like a horrible design to need to be downed to see any form of ecchi, but fact to the matter is that this system was well implement, most of the time you will fall unintentionally, maybe making a mistake and getting surrounded, it even works with some (of the few) proper H-scenes, I think could even be scripted. The animations are very smooth, the stat tracking seems to have some effect, though I'm not sure which, but by the end of the game my character was cumming multiple times from a single penetration, and I was still seeing some new positions, which is unheard off...
The cons here are obvious as well, as I noted above, there are only a few scenes that aren't due to GOR, I mean, those GOR scenes aren't bad at all, but they're practically all samey, your downed heroine getting gangbanged till passed out. Those regular scenes though, they were excellent even if just about +-5 of them, but just looking at the inspiration from VH, and we can see there is a huge potential for much more, I mean just look at that strip dancing scene, imagine how well it would fit for example getting surrounded in an alley, doing some lewd waitressing, going to a mixed bath, going through a lewd maze (like in akakubi arena), doing a escape route (like fort rugoem). It would be even better if these events followed some sort script, like for example the two blowjobs at the bridge, a lot of them could benefit from having a progression. And finally, the sort of minigame (while whoring) could be expanded upon, and its also something they tried to implement in the later versions of Vh, so it could be something light like choosing just what the next position will be (for consensual sex). And finally, I got the last update which already has pregnancy, a nice addition, but again, kind of pointless at the moment.
Finally for the suggestions:
My first suggestion is for him to keep adding to this game, even if through paid dlc, because it got such good ironed out mechanics, but felt shallow in content, specially the ecchi, the most important part here. The design and code of this are already great, all that it needs now is some depth to content, different scenarios, more content that isn't just GOR. Likewise some sort of guild questing system, something to guide the player through side and main quests, could be a heck of an addition.
Regarding the H system, I think mostly all animations and positions are already there, and they are great, however I feel like there should be more ways to trigger them. For example, currently the only way to get raped in battle, is to get downed first, HP near 0, which usually only happens when you're about to lose already, with only a very dim chance of escaping, in the case that you're already surrounded. There was a point where my character was cumming multiple times just from touching even before getting downed, and still they wouldn't rape her. One way to trigger penetration could be very high excitement, and another to just manually allow it, like some games do, to just seduce whatever is close to you. And finally with that, there could a lot more groping actions, some more invasive ones, like oral/tit fucking even before the requirements for penetration are there.
I was also thinking about the EST and ORG meters, and I think instead of the way it is now, that excitement grows through the actions but orgasming lowers it instead of raising. Like being groped for example raises excitement, high excitement makes for a easier target for grope and rape, and higher effect on the orgasm meter (cumming faster), and after orgasm is reached, excitement goes down. It could be a nice way to balance things out. And instead of the succubus curse always increasing it, it would be cool if you needed to keep EST high enough to enjoy the better skills/recovery, this way it would naturally down, but give you a reason to do ecchi, intentionally getting raped to keep stronger, its a gimmick that could help the H gameplay bothways.
I know its very unlikely the dev will ever check out western forums like these, but feel free to send it to him if you feel like it. Farewell
