I kinda like what I see, especially the drawn, comic-like style and the artwork. It's also nice that they have a few different levels at the lower end of the backing range that will give you a digital copy of the game without sinking too much money into the Kickstarter. That's always a plus in my book.
What I am less certain about is the made-up language they use for the game. They say they did it because they wanted the game to have a unique and distinct feel to it, but that makes me wonder if they couldn't have made the game distinct and uinque without resorting to a "gimmick" like that. To me it reads as if the developers were lacking confidence in their ability to make the game stand out through more conventional means. Plus, I would find it a bit inconvenient to rely on subtitles when the whole game is already voice-acted. Sure, it makes localization easier, as only the subtitles would have to be changed, but I doubt I would enjoy constantly paying attention to subtitles throughout the game.
