A couple of bugs/issues.
When you allow Mina to become a remnant, her icon still lingers in the selection menu allowing you to keep pursuing her in the convenience store. The same scene plays each time she is selected after turning. Though nothing happens in this scene, it still costs you the day and can be repeated over and over.
Also, during Marisa's intro she is named Allison more than a couple of times when talking to the MC.
