Lie on front page:
Create
Build needlessly complex machines to do simple tasks ... then blow them up!
Most of machines in TPT is INDESTRUCTIBLE. And creators don't want work on this, for example, don't make SWCH destructible (check this, it's indestructible), same with INST. So lot of elements in TPT are almost fully undestructible (VOID, for example), but need in a lot of machines. Make possibility of destroying machines or remove the lie from front page. No deceive people, please!
Edit: I looked at this in 2021, my post is ridiculous. This is way too advanced for TPT.
use acid, bomb, sing or antimatter. most things are not destroyable in one way ex. insl is not meltable, ttan cannot be blown away, etc. there are ways of replicating invulnerable elemental properties, but it is easier to just use the indestructable elements. :P
