The DIK/Chick gimmick doesn't necessarily mean the rest of the game will be devoid of choices.
It's just gonna be a 4 season drama. 2 years per season, so 4 more years to go.
Sure it has to end, when the developer intended it to end.
At this point it's fairly obvious that the game is being constantly developed (the developer is working full time on this game, so it's a very solid production).
What's already there to play now is probably 20 hours or more of game time. That said, this game probably won't be finished for another 4 years (it's currently at the halfway mark).
It's a great game (depending on your tastes), and definitely my favourite on this site. And while it isn't complete, it still has a lot of replayability in it.
But one thing to understand, this game will hook you in. It's a classic case of, "Came here for the porn, stayed for the story".
Yeah I was only joking about those two.
