Coal Demo Day 28

EDIT: Just posted a Windows hotfix to fix default mouse sensitivity. I dont have access to my Linux dev environment right now, but if your sensitivity is way too low, go to the menu and set them accordingly in the gameplay options menu. If the max is *still* too low, edit the config.cfg in your user folder and edit the sensitivity_x and sensitivity_y values. Now featuring 2 new enemy types, a slightly expanded level 2 and 3, some new weapon models, snapshots in save games, decals, and lots of fixes. And Vulkan! Remember the "frob" key (default F) - you use it to toggle switches and open doors....
