That's the number of updates it's had. 28 updates in 36 months isn't bad at all...
The first part of the game is very, very good. Many players have been unhappy about how abruptly the endings were brought about. This is the second ending implemented and it seems in general to be received well, but the first ending didn't go over as well. If you choose to play the whole game, you will obviously form your own opinion.
It's a classic example of a harem game, so most people are probably waiting for the harem ending which is planned to be the last ending implemented. That frustration of waiting is also fueling the restless atmosphere in the chat. I highly recommend that if you haven't played this game, do so and form your own opinion.
In case you didnt'realize, pregnancy is only in Melody's ending so far, not in the rest of the game at all. Don't want to mislead.
