I've watched the trailer for Atone several times at this point, and apart from some UI elements, I haven't been able to find a single curved or even rounded line in it. It seems New Zealand-based developer Wildboy Studios wasn't kidding when they said it's done entirely in hand-drawn vector art. Here's what else I picked up on by poring over its announcement trailer: the art is good and the music is even better, so Atone is looking pretty promising altogether. 

Atone is a story-driven 2D puzzle game based on Norse mythology. You play as Estra, a young warrior determined to carry on her late father's legacy and save the rapidly deteriorating land of Midgard. A variety of puzzles dot the way forward, not to mention a big cast of warriors, animals, and spirits to talk to.
