This is a video on how to unlock full access in Demolition 3D with a glitch, very simple. First of all, you'll need to choose a building pack (except not building pack 1, and i chose Empire State Building), next click on the drop-down button at nearly the top right screen underneath "Score" and "Parts", then choose photo to take a screenshot, and then click save or don't save button. Bam! Now you can gain tools to move and destroy parts in demo mode.
