At the very beginning, up until 20 Dodges, you can only use the Up-Arrow, but when you get 20 Dodges, you can use the Right-Arrow to dodge the circles.
Right now, I am still working on the game, but I posted it so anybody can suggest their opinion. I am still constantly adding more too it during and after school. My inspiration came from BraveCake, NickAnderson2, Awesome_Aiden26, and all of PopTart Productions. You are welcome to make remixes and check the code for ideas.
