From Adam Poots on the KS comments:
There is a lot of game, packed into this game. It's taken our new play tester nearly 4 weeks of solid full time gaming to complete his solo play through. And that's just the core game. His go to survivor, is a single armed, un-aging dagger master. Everyone so far, has had such a different experience. Makes us really happy to see such high variance
Sigh, only a few more months...
