I kept thinking "why is this impossible, how come the badge is just medium?" Then I looked at a video walkthrough and realized most players don't have the line constantly glitching out and turning invisible 90% of the time.
The controls seem unnatural at first, but once you get used to them, the game becomes a breeze. I wish people would give this game more of a chance before complaining and/or quitting.
I made it so that you won't get full experience when not fighting on your level.
