The story is well-developed with some twist after first third (or half, or maybe quarter, depends on the definition of "plot twist" term). As an eroge derivative, none much expected from the story. Skip this part to avoid spoiler.
Mashiro-Iro's art is quite standard for anime. This might be caused by the tendency to "play it safe" by making the character as normal as possible. The "normal" here is obviously moe for girls and average for boys. The environtment is also well-drawn, but there is a glitch. The cut-down tree in one very small spot, what's the point of having it?? Only the author knows.
The sound is unbalanced, that causes a penalty. Opening Song "Authentic Symphony" in Romaji is excellent, and that song is put on the primary playlist for some anime enthusiasts. Ending Song "Suisai Candy" is fall short of expectation, making that song is the source of penalty. Others are relatively fair with some fluctuations. Effects are standard, skip it.
Character is fine with something strange that causes a penalty. One character that also defy the basic laws is Miu's mother,which one can call as MILF. The character's heights are inversely proportional to their age (WTF!?).
For extreme case, Sakuno and Miu; Sakuno is still 15-16 yet 162 cms tall, she is still growing for another 2 years and she could simply as tall as 170 which is abnormal for Japan's standard (Japs normally have 158 for girls after growth age); Miu is 17-18 and 146 cms tall, that is also quite out of standard. No one knows what's in the designer's head.
Enjoyment achieve perfect score thanks to the fan-service after the second half. For instance, Miu just appeared naked in front of Shingo (WTF!?).
