The rock is reshaped so that pipe is "less jammed" - it's easier to pull it out. Also walls will be breakable with rubble, pipe, box, etc. BTW, wall breaks once certain amount of destruction energy is applied - it could be series of weak hits, couple of stronger hits or a single well timed swing. And thanks for posting replies to questions by other people, really appreciate your help.
Your welcome. I love your game, and don't want you to waste your time on all the stupid or useless questions, if they just can read a earlier post, with the answer in it... It's the least I can do for you beside buying the game :P Thanks for your answers and quick response BTW If you ever need someone to reply to the tickets on steam and questions, you can always ask and count on me.
