While the concept of the game and it's art is amazing, the game is far too tedious, grindy, and obtuse to really enjoy.
Want to advance the plot with a certain girl? Well you need to find her in a certain place, after grinding a certain amount of relationship points with her, at a certain time of day (about 12 hours of the day are implemented), on a certain day of the week, after viewing a certain scene with her beforehand, after selecting certain dialogue choices, and using a certain item, but you only know you'll need the item after viewing the scene once and failing, then finding the shop that sells the item you need, then doing the farming minigame to finally afford the item (one time use), repeat certain steps again to re-enter the scene, and then, finally, now you can view the scene... But only if it's raining (I shit you not). Oh, and you better have gotten to a certain point in your relationship with another, completely unrelated girl, too.
This game is the fucking Dark Souls 2 of Harvest Moon porn clones.
