Characters' body types and proportions don't seem consistent through their sprites and in-scenes, as their body types, arm/chest proportions, and groin sizes seem to change in every scene, and some don't match their sprites proportions outside of h-scenes at all at times.
Otherwise, it's a reasonable enough visual novel-type game. It gives exactly what is advertised, the art and animation are done well, the unlocks aren't all free (this allows for replayability), and the story is serviceable.
