I would recommend this game to people who enjoy grinding in a simulation game such as Stardew Valley or Rune Factory.
I was gifted this game by one of my friends because they thought I'd like it. They couldn't have been more right.

I'd like to note that I have not encountered a single bug in my game thus far, although there are some spelling/grammar mistakes in the English version.

TL:DR;
Great game, constantly unlock new features, riveting story, good humor. Great controller support.
Very grindy and roadblocky, perfect for those unlock hunters and completionists. Each unlock feels rewarding. The graphics and music are gorgeous.

This game has you chasing unlock after unlock, and you run into roadblocks very frequently. To me this is a lot of fun, because you feel so rewarded when you can progress, but there's also no need or rush to progress too fast. This game can be relaxing, and played on your own schedule. If you don't like these things, then don't try the game, because you will get frustrated.
Each time you unlock something the game throws another layer of depth at you, and allows you to progress further. This makes the game rarely go stale, at least in my experience.

I didn't have trouble making money, though at first your resources are slow to grow. Once I discovered some items to get color points (Exp points) faster, I almost felt like I was exploiting the game, because I managed to get ahead so quickly all off a sudden. Then I realized the game still had so much to offer that it turned out to be balanced gains.

As I started this game I was quickly overwhelmed by the amount of things I can do, and I still haven't gotten everything or explored everywhere yet. Even after 50 hours, there's just so much more this game has to offer.

I've only played it with the stranger sins and breaking bread expansions, and I have to say the zombies make life a lot more convenient. While you focus on clearing roadblocks, your zombies make sure you don't run low on base materials. At first I was worried that this would make the game too simple, but as I said, it just has so much to offer.
The Tavern is a huge money increase. I haven't quite made up my mind on it, but it adds amazing story depth to all characters from what I've experienced.

Between farming, cooking, beekeeping, mining, fighting monsters, and of course, keeping graves, it also has so much story, and the story itself has character. It's funny, sometimes very stereotypical in a satirical way, and moreover just a breath of fresh air.
It's also worth to note that EVERYTHING flows into each other. Need to farm plants? Perfect, use them to cook, brew stuff, or use them in alchemy. Faith? Ah yes. You need it for everything. Sand? You can make polishing paste, which you then use to make other things, or glass, or even clean up bloody nails.
Every time I think I have a good grasp on what I can do in the game, the game adds another layer of depth.

The artwork and art of the game is incredibly detailed. It looks stunning. The water and fire are my personal favorites, they look almost life-like, in a pixel game. The buildings look like they make sense, and don't have distorted sizes like some other games have. The designs are also original, and I love the run-down feel of the town.
I love the fact that you get to see the way the town looked in all it's glory, and can then trace back the locations and see how ruined they are in the game you play.
Honestly, props to the people who made the visuals.

The music and in game sounds have been quite enjoyable as well. The music is atmospheric and relaxing, but switches up enough to make it fresh every time you play.

The game is incredibly convenient to play with a controller, as it doesn't use the square grid a lot of games use, and it auto-directs you to the nearest harvest point so you don't have to position yourself perfectly and waste time with that. The only thing that I've had difficulty with, is the fishing minigame. As on most games, it's hard to determine your power output with a controller button. This is a bit of a shame, but I haven't seen a game where they use this mechanic and it has been easy. (Stardew valley has the same style and it's even harder with controller, because the fish can escape.) I mostly prefer playing games with a keyboard, but gravekeeper has such good controller support I don't want to use a keyboard on it.

I've enjoyed playing every hour of my 50-ish hours of gametime so far. This game has me blown away.
