It's not for everyone; the art is its best feature, but it lacks in several other aspects.
It's quite grindy, which wouldn't be a bad thing if the grinding itself weren't so bad. Obviously, the combat and collection mechanics aren't the focus and that's why they're underdeveloped, but given the amount of grinding the game has, they're tedious and you'll often lose interest.
If you can't tolerate gay content, you won't like this game. There's a substantial amount of content that will be blocked behind gay content, and often your character will get screwed even if you don't want to. I'm not talking about losing a fight. You could be advancing a character's story and your character ends up getting fucked in the ass by a futa. You can "turn off" gay content, but that just means you won't see it. It will still happen.
If you're interested in vaginal sex and creampies, this game isn't for you. The creator is into anal sex and futanaris. Also, to repeat the previous point, there's hetero content that might be interesting to you, blocked behind gay content.
I can't recommend enough that if you play, you do so using the guide. You can be a hardcore gamer, but there are things that without a guide you'd never find or know how to do; it's not a truly intuitive game.
The fucking chickens on the farm are the most fucking horrible thing that has ever happened to humanity.
The battles are very frustrating; you'll constantly feel like you're doing something wrong because you can't win fights, and the ones you do win are won by very close calls. This makes getting certain things or passing through certain places feel very annoying.
As I said at the beginning, the art is very good, some of the best out there... but as a game, it leaves a LOT to be desired, and some of the design decisions are questionable. If you are patient and don't mind the above points, then you will enjoy the game, if not, then this game will be one of the most frustrating and unsatisfying you will ever encounter.
I'll start with the disadvantages. The RPG Maker engine and everything that follows from it.It is impossible to complete the game completely without a detailed walkthrough on 100-120 pages. The meaninglessness of some quests (and they take time). I liked: humor, graphics, the option to disable LGBT content and generally a good plot .
I dunno. 10-15? Not that much, especially that you can turn on insta-win in battles (recommended). If I remember correctly, to do this you had to go to the secret room in the bottom left of the basement - just "enter" the wall there
