I just played and I tried it on chrome.
Right on the first level, if I push the ?force? to left side of the screen the ?red line? goes off as well and I don?t see it anymore leaving me without knowing where it is.
When the ball goes off screen, the next ball doesn?t appear right away, I can hear the sound of the ?action? outside the screen but it doesn?t do anything.
I think the difference between green, blue and red is too tiny; the angle of the mouse movement could be a bit bigger.
On the second level, the ball got stuck in the water but I still could move her, is it on purpose?
When I lost on the third level, once I returned to the level menu only the first level was available. The second one, which I won, was still blocked.
