TL ; DR: I'd rate it one star, but I love the art and FMC's look. I'm hoping that the developer's other games can translated because it seems like they may not have combat mechanics, so some of the clunkiness may be avoided.
The best part of this game is the art. I am super biased towards innocent blonde princess knights who aren't stacked to high heaven. The art is a little inconsistent at times, but she's cute, and the art is decent.
Combat is annoying. It's easy enough that you can just press attack until you win (and the magic seemed pitifully weak), but it's difficult enough that you won't have full health when you get to the boss. And there's no teleportation back to town before the boss room, so if you want more items, guess you'll have to trek back through the corridors with the enemies respawned.
Collecting scenes is boring. Fake corruption mechanics, and if you progress the story too far, you may get locked out of scenes without realizing it until it is too late.
But the thing is that these games could be fine because you could just go to the gallery and enjoy the scenes. Ignore the combat and map roaming. However, they messed up that too. The recollection events do not ask if you'd like to watch a particular scene. So you'd better have memorized the sprite of each character for each scene because trying to check which scene it is will launch you into a long scene.
