LightballAdvantage

This is my first time to participate in Ludum Dare. My game is about a small light ball rolling down, rolling all the time. Player draw lines to guide the ball to roll in the right direction by controlling the mouse. Because I have little experience, I am not good at designing checkpoints, and there is another thing that delays a lot of time, so I can only give a game that may not be satisfactory. T.T
