You should add stairs and floors. Stairs will give you access to floors and when you're in a new floor clear out the things you built on other floors. Instead , Show the things you built on that floor. You may have up to 5 floors or probably more. I also found that 2 traveling merchants are in the same outhouse and it's inhumane so pls fix it. By the way can you still access the alpha after you finished the final product?
