Arrow keys for movement. Settings let you edit some values like size, acceleration, gravity, jump force, and others.
I have discontinued this project due to lack of motivation. I started this for a school project and thought it'd be more fun than the other options, but I ultimately didn't finish before the due date. I plan to show what I have here, but I want to make something with actual unique game mechanics, and a more fluid feel to it. (Quick side note, this project runs well on most computers, but I found that most computers with only 4 GB of ram have a bit of lag first loading in sprites and different scenes.)
