Phew finally some forward (or should i say upward) progress!
this new region looks like it has some new interesting takes on digging levels so far
Level 289... digging moves level with super dirt and white blocks
so as you can see the board is separated by 3 regions. The board won't move down until you clear an entire region. By the time you get to the last region, the entire board won't be visible yet, so it'll move down as you dig. so this first level wasn't too bad. I think it took me a couple tries to pass it.
