It's that spooky time of year again, and Cave Confectioner is participating with a Halloween demo that you can access for the next 3 days. There is Halloween-themed content, but as with the last demo, this one is somewhat last-minute. There is a process to access the content.
The process is as follows: Start a new game and exit the starting cave. Collect any item to offer in trade. Go southwest through the ice cave, talk to Mugure, and trade the item for the black rock. Go back through the ice cave and break the rock on a grinding stone (the one by the tree will do). Now you have a knife. Walk south to a small pumpkin patch and take one or more pumpkins. Combine the knife with a pumpkin to carve it. You can then place the carved pumpkin on the ground by pressing E.
If you can, please leave feedback on this blog post. It will help guide the direction of the full release this winter.
P.S. The multiplayer functionality is gravely ill and does not function well if at all. This will hopefully be fixed in time for release.
