Yep, but not actively in that build. Redoing the UI, and going to make some more changes to the way the world is handled then will upload another build.
UI will be similar to the original refmock. Some blocks can be placed by paying their cost in Gravity once unlocked, others can only be placed by the amount of stock you have. Some times will unlock via patterns, others will unlock via transforming them through following recipes of placing tiles on top of each other for certain amounts or in certain orders.
Originally I had the UI as mostly Game Objects and labels but because of this I switched to normal GUIs which will probably be better in the long run… Laggy camera
