This is a difficult one to rate. On one hand, Waku Waku managed to actually make a playable game that compliments it's wonderful art and animations, learning from the many mistakes of Dojo NTR. On the other, it's still a terrible grind and I can't without good faith tell anyone to play this game without at least talking about the many caveats.
For one thing, a lot of sex scenes are locked behind progression such that trying to massage any of the girls to h them is basically pointless unless they are in love with you and you have completed enough upgrades/stats to trivialize reaching the threshold to enter h. If you don't, it's basically a waste of a few minutes unless you want to enjoy the massage molestation - which is mediocre at best.
The main bulk of the game is shop management but it's largely thoughtless busy work, given that as long as you just continue spending the resources to upgrade you never have to worry about failing the 1 billion yen goal. Partway through the game, you get rewards that basically automate day-of management like sending people to clean, who massages who, etc. and another one that gives 2x speed. This is a section of the game that you alt-tab out of and it happens 30 times in a playthrough - incredibly cumbersome. Upgrades to your shop, learning new skills, training and recruiting employees etc. is all generally nothing you ever have to think about, just make number go big. If you are versed in this genre i'd imagine this game would be an insult, as for me, who never plays these types of games, I find it pretty unengaging.
Buuut, there's a pinball minigame! This is probably the most interesting minigame one of these simulator type games has offered. Brings back memories of TWEWY and it's very well made, only found one glitch which didn't matter too much. Launch your character (pinball) around the map and advertise the store, beat people up etc. Not very skill intensive unfortunately, success is largely based on how strong your main character is over thoughtful launches - grinding!! But it's still fun and I never got bored of it.
Beyond massaging them, you can take the heroines out to a bar and this is where you can get them to like you and get them shitfaced for some h-scenes (this has the same problem as the message scenes, locked until max love). Very visual novel-like, talk to them and choose the right options when you do. Eventually, they'll open up to you about problems and you pinball them away. This portion of the game is very solid albeit the slow and annoying rng minigames of rock paper scissors and dice roll to get them drunk before you do. There's items in the game that you get to make sure these games always win and it's a slap in the face - make me play a minigame where i can play to influence the outcome instead of hoping to win the lottery. Without the 100% win rate items, you have to be lucky four times and if you lose you'll end up shitfaced and then the entire date is over. The mc has low tolerance at the start, and so this leads to a lot of wasted encounters if you don't own the items.
H-content is fantastic with animation, voice acting, and a small handful of cgs. There is an exceptional quality and the only complaint I have here is that I wish there was more of the decent amount that we got. A good bulk of the h is massaging, so be prepared to enjoy the slow burn before the hardcore stuff happens. Like I said earlier, trying to push for h-scenes early is often not rewarding so you'll have to be patient before getting to see anything. It took me about 5 in game days before I started working towards the possibility - i'm sure it can be done faster but that's the ballpark estimate of what to expect. On top of massaging and drunk scenes you can put the daughter and mom into the same massaging room to unlock an extra scenario, hence the theme of this game. It was super neat to see this unfold for the first time. The DLC introduces two new girls that you can h in a more traditional fashion to this genre.
The detail and quality in the h scenes is what makes this game worth the grind, should you decide to play it. Although slogging through the in-game days to an ending may take a decent chunk of hours, with half of it probably being boring, I do think ultimately it is worth it over skipping it all with a full save. Waku Waku has thankfully managed to create a game that is worth the trouble to experience. I would however, recommend a guide to avoid pitfalls and make the experience as smooth as possible.
