I have played nearly every Kegani game up to date, and needless to say I was excited when first tracking this games development.
The concept is excellent, with huge amounts of potential if pulled off correctly. Unfortunately, it wasn't. This game is plagued with bad gameplay design choices and a lack of actual H content, both with player and NTR.
Gameplay: The dungeon exploration, the core element of the game is extremely repetitive and unrewarding. It is frustratingly RNG and requires no more thought from the player than clicking the best option available. You either want to see the heroine get fucked faster or don't, the combat is as simple as that. Combat in this game had the potential to rival that of what it seems to be imitating; Nymphomania Priestess. However, this is a very rushed, not well thought out version of that. You go in instantly getting cucked, with no real buildup other than what gets inserted. There's only one combat skill that changes depending on stats and one of your skills (there's 5 buttons to click in combat) doesn't even do anything and just wastes a turn.
On the topic of skills, what was Kegani thinking? Skills require you to perform the action or level the skill with gold out of the dungeon. The problem is the grind for some skills is unbearable compared to other skills that level relatively reasonable. In order to see a lot of the H content you need to level the more difficult ones, or you will literally see and get nothing. On top of that, you cant just continually level up skills, as there are strange skill cap checkpoint that require you to spend more and more (up to thousands worth of gold) to be able to continue leveling the stat. Combine this with dungeons who's lategame counterparts dont even give you the reasonable amount of gold for time spent, and you get gameplay that is repetitive, frustrating, and boner killing.
H Content: Now, I haven't seen everything, but I don't care enough to keep grinding to get a full completion. The girl is hot and all the art is pretty good, some minor animation, Kegani at least gets better with art as time goes on. The story going straight to explaining why the protagonist lets the girl get groped and more right off the bat is just lazy, and it happens every turn, there's nothing you can do about it other than stopping her lust from rising and protecting her clothing. Getting cucked while going through the dungeon and peeping on it is the hottest shit that's in the game. Unfortunately, I've got no idea how to get it to happen other than hoping the antagonist randomly rolls the event. Outside of the dungeon, the content is really bare bones and requires the girl to be trained which is a grind in of itself.
OVERALL: This game has great concept and potential, but it falls short of what it could be. Kegani needs to to maybe slow down and actually work on making a good game rather than dropping rushed half made games that are annoying to play at times. I say this hoping that this game receives a lot of rework and development because I'd love to see this concept actually pulled off correctly.
