As a first-time player, I enjoyed myself immensely. Eventually, anyway.
Honestly, the start was a little hard to get through, primarily because of the MC. While he didn't seem like a wimp, he did feel overly passive to me and not at all what I would expect a detective to be like. Didn't ask enough questions, didn't seem curious enough, and trusted too quickly. I was pretty sure he would get murdered two days after he gets assigned a case where the culprit actually IS a cute girl.
I also didn't like how he didn't literally take his gun everywhere after getting almost killed twice and finding out myths are real. I mean, yeah, you're going on a date with a girl, and bringing a gun is not usually your first instinct, but when both you and the girl have already been attacked multiple times, maybe it's a good idea to bring some protection! Even if you're on a date! Personally, I would have gotten a second gun, just in case.
I also felt he dropped the mother topic with Uraha too quickly. I mean, my mother is alive and well, but when a 500-year-old vampire tells me they "heard about her," I'd like some more information than that, let alone if she were dead.
Then, some minor things, like during Miko's date, where the MC gives her a box of chocolates that seems to appear and disappear into thin air. It's kind of funny when such things get acknowledged, like the MC thinking where they pulled this and that from, but when it's not, it's just weird.
There was also the time when the MC had already told Miko about Suzu staying at his apartment but later worried about telling Miko that exact same thing.
Anyway, having said all that, from about halfway into where the game is at now, I started enjoying myself a lot more as the MC started seeming much more like what I would expect someone like him to be.
I still have some grievances, though, like the MC still having failed to check the handwriting in that notebook. I mean, yeah, the case is basically over, but be a little more thorough; why don't you?
He also still has too many times where he "Doesn't know why he did/feel/say/think this or that." Even if it has gone down by a bit.
Like the time when he "Didn't know why he felt like kissing her," and I'm just sitting here thinking 'dude, you have a beautiful girl on your lap with her face close to yours while you're looking into each other's eyes. I would have revoked your straight male card if you didn't at least THINK about kissing her.'
It seems I somehow ended up complaining about the MC again, but I honestly enjoy both the MC and the game now. The setting and story are both intriguing, and I'm excited to see more.
There aren't really a lot of adult scenes yet, but the ones that are there are good, and I see a lot of promising stuff for the future.
