Wow. Great, meaningful game.
For everyone wishing it had "ended" a different way, consider it to be like a book. Even though you may hope for a better ending, or for it to change, what the author writes is final. In this case, it forces the player/reader to figure out what actually mattered in his/her "last chance."
Really cool concept. Something, though, seems to be lacking. Part of it is definitely the bad translation :-P.
Some other points:
more money (I was on day 8 and still had only managed to buy the TV)
get rid of payment for original three (not paying them changes nothing)
There's some element of fun that's missing... I can't put my finger on it.
