Good art. That's kind of it really. I downloaded this game a while back but never finished it, then decided to play it again recently and realized exactly why I didn't finish it the first time around.
While this game is fully focused on the harem aspect, to the point where there's no art for each of the individual girls' endings, it's really not worth it to go for all of them. If you play this game, just pick whichever one or two girls you whose route you wanna see the most, do their route, then you can stop playing.
The main problem with this game is how little it respects your time. Holy shit. The grind. A playthrough of this game will take like 4 hours to fully complete, but if you took out all the pointless money and stat grinds, this game would last like half an hour. Yes, it's that bad. Here's an example, if you talk with one of the girls, you get 5-7 affections points. To fully complete any of their routes, you need 300, so assuming you get an average of 6 affection per talk, it'll take 50 talks total. Each interaction costs 25 of your 100 daily energy, meaning you'll probably take until day 13 to max out a single girl's affection. EXCEPT YOU WON'T!!! Because on top of that, each girl has a secondary stat that you'll need to reach at least 40 of to unlock every scene in their route, so considering how you have to grind for them too, it's basically impossible to to fully complete even a single girl's route on a first playthrough... unless, of course, you grind even more!
So, the main thing you wanna do first is get all 15 trash on the beach and give it to the trash collector, and find and return the sunscreen for the woman on the area to the right. This will give you 600 yen, which you can use to buy 2 waters, which recover 30 energy. Then, you work part time at the restaurant, which costs 50 energy and gives 800 yen, and puts you in a 10 second unskippable cutscene. Keep working part time and using water to recover energy, then buy more water bottles for working more. Keep doing that until you have 15k or so yen, so you can the amulet of goodwill for 3000 yen, which increases affection gained by talking from 5-7 to 8-10, then buy as many waters as you can. Gifts for the girls are pointless. The most expensive gift is also 3000 yen, and increases affection from 16-19. You could instead buy 10 waters, which give you 300 energy, for 12 talks, which, assuming you already got the amulet and get the minimum amount of affection every time, will give you 96 affection.
So anyway, after grinding for like 20-30 minutes, feel free to start the route of whatever girl you wanna go for, talk to them to increase affection, use water to recover energy, keep going until you reach the next scene, which will require 10 of any given attribute. You can grind more money for the books that increase these attributes, though it's not necessary for charm and playfulness, since those you can just get from the kids or the chads, it's 25 energy for a 2-3 increase, which, if you have enough waters you can get 40 by day 1. You get kindness from working at the restaurant, so if you grinded for money you already have it well above the threshold. Sex appeal is obtained from finding hentai manga around the beach, there's 5, they respawn every day, their locations are fixed, and they give 2-3 sex appeal per one you get, so you probably won't take many days to max it out without the books. Integrity sucks ass to grind. If you get all 15 trash on the beach each day, you gain a whopping 3, meaning it will take you until the literal last day of the game to get 40 of it. Just grind more money for the books in the shop, it's faster that way, but not more fun in the slightest.
What else... there's like 5 songs in the game, they're serviceable, but I have grown to resent all of them because they're played in an endless loop for 4 fucking hours. The story is you go to beach to get coochie and then you get coochie. Each of the girls have like 5 lines in the talk action, which you're gonna see a billion times. Sexy talk is talk but worse, you get less affection from it than regular talk for all of the girls, even the more openly promiscuous ones who would make sense to give more affection from it but nope.
So in conclusion : This is a fine, if basic 20-40 minute game with good art and varied love interests, stretched into a 3-5 hour slog of a game thanks to a ton of pointless grinding and time-wasting bullshit. You can have a decent enough time if you only play the route of whichever girl interests you the most, but going for the harem ending just isn't worth it whatsoever.
