Press space. It can't really zoom in more than 200%, if you can't read it and REALLY want to know more about it, see inside for details. (I sound like a salesperson). Study for science guys. It's hard once you get farther into it.
Just me. I didn't really put music on because it prevents me from studying, and I know I could just press the mute button, but I was lazy. Constructive criticism is always appreciated! If you like it, please leave a love! :D
