This game... best way to say it is it has great parts and terrible parts.
Art
Images for scenes and such are great, if sometimes inconsistent in details. Like the kimono showing off her breasts, then switching to completely covering them the next scene for no reason. The pixel art sex scenes is nice. The pixel art for the x-ray cam and face cam feels very lacking. Like there's one where you fuck her from behind and there's a camera to the side showing her back. She looks like a sheet of paper. Completely flat. No shading or anything. Her face cam has the same problem and her expression barely changes. Then the onsen has her be a more... cartoony(?) style. Except it looks like they're playing the animations on 2x speed. Which is weird. Game basically switches between 4 different art styles.
Gameplay
Very grindy and buggy. Remember to run Rei Patcher. Reduces the issues, but still buggy. Also make frequent saves, since the game has a tendency to black screen when going from voiced dialogue to an animated scene. Minigames everywhere and it's like they're designed to be as annoying as possible. A lot of them need you to look at a bar and adjust it, so you can't even enjoy the sex scenes. Rock paper scissors color coding makes no sense. Getting her to high enough lust makes sex free, but then it randomly switches to needing money.
Collecting images is also a pain, since some scenes give you images for another scene, and sometimes the images just don't save to the gallery. There is a full cg save file included in the game folder, as well as a walkthrough. Hint system is pretty bad. Like it'll tell you that you can't do this because something else is "higher priority", what is "higher priority"? Ask the guide doll, 50/50 chance of a proper answer (this is properly bad translation's fault) so you have to go to the walkthrough anyways.
The text messaging takes a long time and is unskippable. Also resets your last conversation if you load a save. Like if you text, save, and load. It acts like that conversation never happened.
Story
Idea is nice. But very rushed. Doesn't really feel worth it, especially after all that grinding. Translation is bad but mostly understandable. Issue is buggy game has a 30% chance of skipping text boxes. So you have to replay scenes multiple times to see everything. Translation also cuts text. Like the english translation often has just one sentence, while the voice acting goes on for a whole paragraph. Writing also does not match up with the animations. Like the sex scenes. The text may be talking about missionary to doggy style, but the animation shows doggy style to missionary. Happens pretty often.
I recommend that you just download a full save. Or use the full cg save the game has. You'll be missing context, but the incomplete translation along with random skips of entire text boxes means you'll miss context anyways.
