Thanks for the reply! These are things I've definitely considered, and I understand that Player 2 has a disadvanatge in controls. That's partially why I added controller support, but I kept the keyboard controls in case some people didn't have a controller. It would be a pain to add editable controls, but I would be willing to add it if controls become a major issue.
I'm glad you're enjoying the game so far! Stay tuned for more updates!
