Originally I worded this a bit crudely, so I will change it.

I dislike the MC because her decision making does not make sense. I am a very logic oriented person, and there were just several moments where her thought process and decision making did not follow any kind of logic. It just felt like she was dumb for the sake of moving the plot along, and not actually making a genuine mistake. 

The writing in this visual novel also doesn't read smoothly, it does not  flow. It has been a while, so I can not think of a particular example but it was distracting.
