This is a simple concept where you are a ball on a circle that resizes according to your mouse. The ball will follow your mouse along the outside edge of the circle. It HATES the bottom, because it's afraid of heights. If it gets to the bottom, It does a 360 but ends back on the bottom. It's weird but I couldn't work around it. Have fun, and use the mouse! :P --EDIT-- Thanks to @asivi and @Rokcoder , I've found a solution, and it will be used later. For now, deal with the glitchiness that is the game.
I was originally gonna have the circle appear as you went over it in some places like the PC game "INK," but decided to not. I could have if I put more work into it, but it's not a game, It's a concept. Other than that, Idea is by me. Sorry for lag, Its a lot going on. Its cause the circle is made of 100% pen and is constantly being created.
