Orbs? More like apples. Anyway, The first thing for you to improve this game is to STOP putting pointless ads all over your game. It's annoying how I keep on clicking them because they're blocking my way. Especially the last level. The entire screen was filled with ads! Also I got annoyed when a new tab appeared showing BOB THE BUTTON 2 on Kongregate (which is my favorite flash gaming site by the way) when I finished the game. Next, I shouldn't be able to draw "orbs" when I press the start button. All of the levels became over 9000% percent easier because of this and this also makes it less of a puzzle game and more of an action game. Third, try pressing the "center" button on the apple (orb) sprite so that the apple appears right in the middle of the mouse when drawing. Fourth, don't allow making apples (orbs...) on the ball because this causes the game to lag, and also makes the ball stuck. Lastly, avoid using the game information as your start-up menu. (I know all of these things because I use Game Maker as well)

Maybe less apple like circles, and why do you use that blue circle in almost every game you make?
