Quite a grindy game. 100% (I think?)-able in maybe an hour+. At least, all costumes, hairs, hair colors, and positions. Remember the TLDRs are at the bottom.
Gameplay, 4/5: Decent, but a Bit Grindy.
So the core gameplay loop is you do a coin shooty game to get money, then use said money to buy everything (drugs, positions, etc.) and you NEED to do them to unlock the costumes. You avoid shooting red coins, until the very last two bonus stages. You also have to meet the requirements to beat the stage i.e. get 40K coins, etc. You also have to manage GF's stamina and mood by giving her food, doing drugs during sex, or upgrading it. The "challenges" are not hard, which is great, considering...
You need to grind millions of coins. You can NOT repeat all of them for coins, only certain levels. On the best level, you can make AT MOST, 180,400 coins. And that's about a minute. You save time by not getting all bonus times, and speedrunning it, basically. Lose a few hundred to save a few seconds. And you need 1,000,000 for the most expensive position, not including the purchasing of literally everything else. Of course, you make a few money by completing the stages up to that point and beyond, but... Reloading also gets interrupted if you as so much as TAP a direction. It's a fast reload, but given the challenges, it feels like a lot.
Some extra notes, your points cannot go into the negatives, so the last stages (if you want to play yourself) you can shoot the red coins to make it easier to shoot the actual crystals or coins, and then do so, and you'll reach the requirements. Oversight, I guess.
The pistol has, I think, infinite RPM. It shoots as fast as you click, while remaining perfectly accurate. Use that knowledge as you wish.
The H-Part of the game is OK as well. A little bit confusing at first, but, to keep it short, let's just say it's not as good as other H-Games due to pacing, and STAMINA management.
Overall, the gameplay isn't bad. It's just grindy, with a few faults.
Visuals, 4/5: A Bit Amateur-ish, but Still Cute.
The screenshots is what you get. It does not look bad, but it does not have that level of polish some other anime porn games have. The nipples also look mildly weird, and during missionary, there's obvious distortions on the top right where her phone and bag is.
X-Ray does not apply to every position, too. Anal X-Ray is mostly out of the picture as well.
There's plenty of costumes, but not hundreds, obviously. That is fine. Hair options however, are limited to four. Also, you cannot edit breast size, height, weight, etc. That would obviously put a lot of strain on the animators, since it's probably Live2D and hand drawn, but otherwise...
Audio, 5/5: Great!
Ambient music is fine. Brownie points for not really sounding stock. As in... The ones used in like, 90% of other H-Games. Some sound effects are, however. But it's few. I think. The VA is fine. The audio is clear, but quiet (one of the whisper-y type characters). It's not awkward.
Story, Not NTR/5: "I Can't Believe It's Not NTR!"
Your relationship with your girlfriend is stale, and boring. So the merchant from RE4 becomes hentai and helps you have cosplay sex with your GF to repair your relationship. And you pay with the magical floating coins. IDK how inflation doesn't occur.
Overall/TLDR, 4/5: Good, but Not Amazing.
As an independent/small development team work, it's really good. For a big team, not so great. The gameplay is limited; what it does is alright, but grindy. It's a basic side-scrolling objective shooter. Options are limited, and some options are not universal i.e. x-ray. Audio is arguably the best part, and visuals are a bit messy here and there. You won't get any tear jerking story nor H-scenes, but as I've said, it's pretty alright. Another H-Centric Game. Better than average.
