Luckily Dora and Lich didn't end up dying by cave in. Lich easily threw the flooring around and destroyed all the spikes. Using the G state ability, the amount he dug up at a time was in a massive range.
After zigzagging for awhile, the two escaped the 2nd containment and moved onto the next one. "So it was just a floor down. I could have saved us some time by digging straight down." Dora said something that made him realize it was a good idea he didn't dig down.
"Well the bouncy bed level was big. The entrance to this place is far from when we entered. Even if the next level is just as big and covers the entire same area, if you dug down like how you dug around, we would of bypassed the next level entirely."
Keeping his mouth close, Lich stared at Dora until she explained the next level they were going too. He realized something was off as she waited until they went down the stairs and saw the next level before explaining.
