@DJMcSpookem I'm kinda ambivalent about it. I like the fact that you can go back to old problems and find new solutions with your new tools. But it does mean that the leaderboards are pointless until you unlock all mechanics.
@DJMcSpookem nice work. :D I generally stop optimising cycles in Zachtronics games after a while though ;)
@DJMcSpookem usually the golfy things, so blocks and footprint in Infinifactory, but generally I tend to optimise early levels, then play through the entire game without optimising and then maybe go back and optimise a few more.
I still need to finish that game though. I stopped in what I think is the final set of levels.
