Click on the balls! The yellow ball gives you one point and then multiplies. It goes at 1x speed. The red ball will delete one yellow ball every time its clicked as well as take away 1 point. It also multiplies. It goes at 0.5x speed. The blue ball gives you .5 points as well as multiplies into 5 more blue balls. It goes at 2x speed. The green ball flies around and paints its path. It is worth 5 points but goes at 10x speed. The rainbow ball appears in the first 60 seconds and will not respawn but gives 10 points. It will fly across the screen and you have 3 seconds to click it.
I'm just creative :)
