Goo
Goo is a builder's swiss army knife!
Right clicking a block with goo will put some goo on that block. Click on a block with goo on it to spread more goo around. Punch a gooey block to remove the goo from it, and the goo around it. Shift-punch a gooey block to remove just one goo.
Mining a gooey block with the appropriate tool will mine out all of the other gooey blocks with it.
The gooey blocks can be replaced by clicking on them with a different block.
These two operations have a small chance of causing goo loss.
Shift-clicking a goo-freey block with goo will move the other gooey blocks in that direction.
Clicking & shift-clicking slabs and stairs with an empty hand will rotate them.
