Same way you came from

Well it stands to reason that if you dug here the best way to get out would be to burrow there, the key must be your pickaxe you just have to figure out how to reach it. Let's see, squat and stumpy, abysmal stats and can't jump very high... But you do have a nutty crafting build coming up so stands to reason that is your ticket to freedom all you need is...

Wow... Thats alot of rocks, you're not sure how you would be carrying it all but put it up to an anomaly based on your previous digging task. It seems you even managed to burrow through some rare minerals on your way here, and examining the expansion symbol next to gemstones you even find a good mix of gems though only 17 diamonds that looks to be the rarest of them. This is excellent however just what you need to be able to reach your pickaxe up in the ceiling corner, all you would need is some stairs and after dropping a couple of stones on the ground and some quick experimentation to find another menu to select buildings. Good gold there was alot of options, chalk it up to maxed stonecrafting why you have access to so many variations of hallways and mineral based structures but regardless you got to stay focused until you get out of here. Selecting the simplest stone stair from the small pile of rocks menu it flickers away before being replaced by a new one.

Of corse you will build it! Smashing that green menu button then cursing as your fist pass through and hit the rocks, you do notice the menu changing once more to say something else.

Well, well then thats not too bad so getting to tapping on the rocks while humming an old mining hymm to yourself and watching the bar fill up in short order. Once reaching just one tap away from completion you cant help but giggle feeling the corners of your beard curve up with your grin as you swish your finger aaand!...

You have not claimed this land, you cannot build here. To claim land, find a Claimant Crystal

"SON OF A DITCH!"

Slaming your fists into the ground and letting out an incensed huff as you glare at the pile of rocks, then up to the ceiling and drawing a deep breath as you stand up stroking your beard. Reaching out with your foot and taking an experimental step on the rocks you can at least confirm that they are solid. Having another idea then you tilt your head with a growing grin, if you can't build here then why not just drop a pile of rocks big enough to climb up on?
