This is a weird one.
First things first, the story is actually pretty deep and rich. The characters are likable. It does drop some memes here and there that imo don't fit the atmosphere and theme, at all, and while I personally didn't mind them, I laughed even, they can completely break the story for some.
Also, if you like having choices this isn't for you. Game is completely linear. I'm several hours in and haven't get a single "real" option. Sure, games let you click on "talk" to the characters and "leave" an area, but game would be the exact same without those. You don't really have a chance on how the game plays itself. So far at least, but these many hours in I doubt this will change, and if it does game seriously needs a disclaimer at the start to let you know you'll get more freedom later on (really later on).
Now, over the reason why I even wrote this review and why I say its a weird VN. The problem here really is the adult content, or more like, how much (or little) of the game contains adult content. I feel it hurts the game more than it helps it, relevance and popularity wise. The game barely has any adult content, so peeps who will find it excepting ero content could, potentially, be extremely disappointed. To market a game as ero yet to barely have any ero is no good. Yet, the game does have some adult content so it can't be advertised as a regular, all-age appropriate, VN. And this is why I find it to be so weird.
OoT does a lot of good stuff, but falls in a weird middle where it doesn't really cut it for any market. It isn't really an ero game, if you come here expecting that as the game main focus, you'll hate it. Heck I'm several hours in (more than the amount I give most VNs) yet there have been only 2 scenes so far, and they were pretty lackluster erotic-wise, as they weren't there for erotism really.
Let me repeat that, this game ISN'T an ero VN, as much as it is a romance VN, with some adult content here and there, which also feels like its there for the sake of it. Which imo, does an undeserve to the game, as just a single adult scene makes it unsuitable for most audiences.
This VN would be, imo, better off just cutting entirely all adult content (which would amount to less than 5 minutes of content so far in my game) and just sell itself as a regular romance VN with some heavy themes.
Feels like authors needs to decide what they want their VN to be, because, so far, it really isn't anything in particular. Almost feels like they simple added the adult content cuz that's where patreons are (which is understandable). Because game certainly doesn't focus on ero content at all, and it doesn't even need for what is tbh.
If you remove what little adult content there is, you still have a pretty damn good VN.
I wouldn't be surprised if once game is finished they'll just go and cut off the adult content and release it on steam without it. It has potential to do good that way, cuz it most definitely will miss the mark if its sold as an ero VN.
