This VN is by the makers of Pure Girl, Innocent Girl, and the Grisaia series... Front Wing. As such, I couldn't ignore it, since it turned out not to be a nukige... though it feels like one toward the end of the heroine paths.
To be honest, I didn't have any hopes for this game, so it was nice that it had such good humor in it - think Pure or Innocent if they weren't nukige. I'm keeping this short because playing this game got really stressful in the heroine paths, and it is a bit hard for me to be spiteful here.
To be blunt, the structure of this VN is classic 'normal' charage. The common route is about two thirds of the game, and it is used for introducing the characters and building the overall dynamic and character relationships... and the heroine routes are straight 'fall in love>ichaichaichaicha (insert infinity sign here)'. The sad part is that the common route is really high quality... but the heroine routes are so unbalanced toward the newborn couple making out that I wanted to puke sand.
While this isn't VN of the Month quality, it is more than enough for your average charage/moege lover.
