Hi, I'm the person who left a review on the previous version of this game after having DirectX problems. I like this remake better, though it still keeps a lot of the issues with the plot from the visual novel version. One other thing I didn't like was that the contrasting black-and-white tiles on the floor hurt my eyes to look at.
However, it seemed to be programmed well; I didn't notice any bugs, though I didn't really look all that hard for them. I also liked that Michiru realized the consequences of her actions in the bad ending.
Anyway, I wish you luck in your future game-making endeavors!
