Using my automatic digging robot, I reached the layer just above the green acid.
Then I dug some more, and saw that I could not reach the acid layer, nor could I have access to any “hanging thing” to go down. Nevertheless, I was able to reach the acid itself by dropping loads of rolling voxels until I could reach them.
However, the rolling voxels seem to float on the acid instead of drowning, so I’m back to the initial problem: I’m standing of my raft of rolling voxels, but still unable to attach voxels to anything below, for the lack of anything reachable.
“Why?”, will you say… I don’t know. I just want to explore :-) And the challenge, too.
So, anyone managed to go below the green acid without bypassing it through another zone?
