Loving the update so far, the new base is gorgeous yet terrifying, just had a couple of tweak suggestions (spoilers ahead for others who may be reading):
Tweak Suggestion 1 - Allowing the static blood splatters found around the base to be cleaned.
Tweak Suggestion 2 - Adding some way to manually fix/repair the cracks and holes textures in the walls and floors.
Tweak Suggestion 3 - Allow the cancelling of wall builder brick placements.
Tweak Suggestion 4 - Maybe make the caves just a biiiiiiiiiit easier to navigate and explore. Getting the radioactive crystals seems a lot less viable when you have to delve through kilometers of winding tunnels to find them.
Tweak Suggestion 4.5 - On that note, unless it's not already in and just don't know about it, add a tool or function or special cave object that can bring you back to the start of the cave. For now, the only way to get back is to press the numpad period/delete key and ragdoll as you fall.
Tweak Suggestion 5 - Add an option in settings that allows you to see the sell price of an item in your inventory.
Tweak Suggestion 6 - Allow us to do SOMETHING with the empty pots, the ones that we find around the base. I don't know, let us craft it with a pinecone or something and we get a potted shrub, etc.
