The difficulty is absurdly hard, to view any H-scenes you need to fight enemies on this absurd difficulty, the game says completed but it seriously feels like a tech demo because there's 4 enemies to fight in the entire game, and to make any progress you need to use special hard to obtain cards to finish off your enemy, and you need to also fight this game's RNG system of giving you cards, even if you used a save editor and gave yourself a million gold you still won't have fun.
Oh and did I say there's no gallery?
Some story progression, more H-scenes, an actual shop for cards and maybe this would have been a 4/5, but the way it is I just can't rate this higher.
