Epic had an interview with the lead dev and he's claiming the focus is shifting somewhat for release:
"Last September, you described the game as an action-shooter roguelike, but it's changed dramatically since then. How would you describe Witchfire today, and why?
Chmielarz: See, that's the first issue. We never called it a roguelike. We called it a roguelite. ... But then we started introducing other elements, like non-randomized, hand-crafted dungeons called Vaults. Long story short, we realized we were making an RPG shooter, not a roguelite."
