I loved this a lot! The art and story were both amazing, so I completely disagree when you say they are low quality ^_^ I think you did a wonderful job! What helped a lot I think is that all the art was consistent, giving the whole game a more professional feel. The music was also chosen perfectly, including the change of music at the end. Very well done :)
Clicking on various items in the room and learning about the life of this kid and their dad was very wholesome, and the two cutscenes were just amazing. I would have loved more cutscenes, but completely understand the time constraint >_< In the end I chose the painting over the ruler because I felt like it had more emotional weight.
All-in-all amazing job! I honestly don't really have any critical feedback. I enjoyed every bit of it :D
