I think I really like the concept. The stylized artstyle is so amazing and the story is chillingly good. When there is an audio it is also good. I think it conveys the experience of emotional abuse really well :3
Like most point and click adventures though I suppose this suffers from similar problems; mainly that sometimes I as the player don't know what I can do and what I should do - this is the problem with basically all point and click though so I'm not sure what you can do about it. This gets even harder though the more "junk" items you give. For example, was there a reason why you put the toy mouse? I did not catch any significant meaning to it, but it clutters the inventory. When I got the paper with the call for help I tried to combine it with my dead phone and with the phone in the parents' house too but turns out I couldn't.
Perhaps the biggest problem though is when the text from the narrator overflowed from the black screen above. I think the text box can also have more polishing.
