So for the positives, the models are really good, animations are great. And I like it.
But now for the negatives :
Game full of memory leak, the arrows to travel the map are horrible to click on for a lot of them, the super slow book animation.. If you click to fast the game consider you're out of the minigame and start new harvest that ends up by blocking you completly. Some areas will instantly give you error. If you alt-tab you cursor can disappear. Like holy f bro I think I never played a renpy game that messy.
The secret scene to beat the AI chess is just bad idea in general. And after the chess and Hana's scene, the game suddenly starts to be super slow, like it wasn't slow enough before.
I always wonder why people are not just making a novel and feels the need to create super messy game awfully optimized and super grindy.
