Testo Squares

All I see is squares
Ones and zeros in the air
Not sure how I got here
Is anybody there?

Something draws me to a tree
Compelled to punch the blocks
Somehow it doesn't hurt me I'm stronger than I thought

Am I really alone? Am I the only one?
I should build up home, before the sun is gone
Punch a two by one, tunnel in the ground
Make a couple doors with the wood I found
