I was quite relieved that it was not as sad as the comments mentioned. I didn't want to cry, but still wanted to play the game. It's quite the opposite actually. I had to laugh at the homework part. o(*￣▽￣*)o
For the art style I think it was beautifully made.
Suggestions:

For some it might have been cool to choose a name for the doggy. Especially when they lost one themself.
