See crafting elements and more in this fun trailer for Dropkick Navvy, an upcoming physics-based crafting/survival sim game. The Dropkick Navvy: First Step demo is available now on Steam. In Dropkick Navvy, scurry, gather, and build to help your pal the World Tree reassemble a broken cosmos. Which broke all on its own, totally at random, and no one in particular was responsible.
