Necromancy aside, Bone's Cafe has you really digging in to not just the layout, but the format of your restaurant. You can customize where kitchen elements and service is, as well as the menu, letting you decide the concept or theme, from pub fare to fancy eating. You can also buy specialized tools and equipment that let you change how quickly certain dishes can be made, or set up a more efficient skeleton-powered chicken frying system.
Bone's Cafe has both a campaign mode and a challenge mode. You can play it with 1-4 players in local couch co-op, and you can use Steam's still-amazing Remote Play Together to allow just as many people to play over the internet using just a single copy. That's nice, isn't it? Lets one player focus on murdering customers while the other manages the kitchen.
Bone's Cafe is available on Steam for $15, and you can also find a free demo there. It's self-published by developer Acute Owl Studio.
