No need to be sorry! This is great feedback. :)
Since this is a puzzle game, figuring out what you're supposed to do is actually the core gameplay. And guess what? With "matching the pattern on the left" you've already made a huge step in the right direction!
"Also the I couldn't understand what anything did.": If you don't mind spending a few more minutes on this, could you list your best guess of what each of the twelve tools are doing? As the developer I obviously never had to go through the initial explorative phase of the game, so getting feedback about the learning curve is incredibly valuable.
Thank you for giving it a try!
