The game is one of those you pick up and play in a rainy afternoon, along with some coffee or hot chocolate. The art is kinda cute, not my cup of tea, but I still can see its value.
Gameplay wise, it's really, really simple, so I guess the Story was intended to be the main focus. Speaking of, the transition from sweet to bitter happens a little bit too fast - at least for me.
More focus on the characters themselves could really help the game presentation, in other words, it's always better to see an event than hear a character talking about it. The most sad moments could be powered by quick flashbacks, maybe just some flashing images on the Screen - anything that would break the "dialogue, dialogue, dialogue" flow.

The message behind the character's fate is really strong and makes us think about it for a while, so if your main point was to deliver it: mission acomplished.
