I really liked this game... The meaning behind it is deep, the graphic makes the situation sweet but bitter too.
I enjoied a lot this game even in its simple gameplay and short puzzle.
[SPOILER ALERT]
I liked both two endings, obviously they shows different sided based on the choice.
The graphic was beautiful and well made in the endings too, the music helped a lot feeling the scene. Very beautiful, really.
Like others in the comments section, I wished to explore more of the game, more rooms, look more around.
I'm sad it was short, it was a wonderful game experience!
