Rakuru: Yeah, the DLC chapters would supposedly be free, but I would still worry about them actually being able to finish all of the chapters and the storyline. It looks like their Kickstarter promises a new 3 - 6 hour chapter every 2 - 3 months, which also sounds like a very ambitious goal for a small indie team. They promise
more than 20 additional chapters after the game's release, so even if they somehow manage to squeeze out one chapter every 3 months, that's a minimum of five years that the players would have to wait for the conclusion of the plot. For the dev team, it means five years or more spent working full-time or more on
free content for their aging game while they could have just made a focused 30-hour game that's complete upfront and spent the rest of their time developing a sequel and having more freedom to actually improve and change the engine/gameplay.
Ach, I didn't notice this aspect of the planned release. It does indeed sound like pie in the sky, and I wouldn't be surprised if after the initial game release the devs went "Well, sales aren't what we hoped, so it's with a heavy heart that we have to cancel the rest of the chapters". Perhaps if they were an established studio this plan might be feasible, though that's a ton of content updates even then. I don't know of any game that I've played which went beyond 5 DLCs that meaningfully extended the storyline.
