The following review is based off my personal experience with playing this Game/Visual Novel... I try to be as brutally honest and detailed as I can, and these are my own opinions and thoughts, from one or more play throughs... The version this review is based on is v1.20 Demo...
This is basically nothing but a sex simulator game demo, which is just meant to show some mechanics of what the story game will contain...
Visuals of the characters are 3D with panoramic camera view, all Hentai, most likely made with Honey Select Studio... The backdrops are all unique and of the same average Honey Select type quality... You can change the camera angles, and there is your typical sex sound effects found in most Hentai type products... The male character is a see-through ghost with no noticeable features...
The script is non-existent as there is no story mode in this game... You get to play what is commonly known as a free-play mode, with no story or real end... You get to select from a choice of sex positions (i.e. bed, chair, etc) and from there you have a selection of sexual acts to perform... Not all are available... You can select when it stops, pauses, and once all the right stats are achieved from the sex act, you can select how to end it... Once all the woman's stamina is gone, a new days starts... You can also select different toys to play with, etc... This is very much a sex simulator, and that is about it...
You do get to see some of the mechanics of what is used during story mode, which appears as though you are doing sex acts to gain money from viewers, in order to purchase more equipment and sex act locations... With certain stats to increase, etc... There is no telling from this Demo if there is any sort of actually meaningful and/or deep story associated to the game play of Story mode, but I seriously doubt it... It really looks like the Story mode is the sex simulator with progression... No way to really tell fully...
Overall, this is purely a porn fest in the form of a limited control sex simulator... Totally intended for masturbation, and that is about it... Don't expect anything else from this game demo, at all... I will definitely not revisit this one...
