As long as you have plenty of access to wood, it's plenty feasibly to make walls around caves and such. It's not good for housing or many large constructions, but it should do until you figure something out.
I can already tell chazbothegr8 is going to die by a cave-in, which will force CG62 to go insane and murder almost everyone, but she will suicide after killing the cook and we will all starve except me. I will trade my goods for food after running away and living in a town. This is how Cliff_Racer will lose.
