This update doesn't bring many changes, but I am proud to say that I'm making progress on the tech tree and costs for each workshop.
In the following days I'll be adding more recipes and a few stone-based items.

Changes:
- Fixed some issues with selecting trees to chop up a hill not working correctly.
- Added stonemason and sculpture studio.
- At the sculpture studio dwarves can make statues of the following: dwarf, sword, shield, cat, dog, pickaxe, shovel.
- Added a background image to the main menu.
