Well, not sure if I'm on "some computer", but it has major issues on mine. Playing on Windows 10 / Chrome. I can drag from the ball and let go and I think what I hear is the ball moving and bouncing against walls, but the playing field nor the ball are updating. So it's basically unplayable.
Sometimes it does update and I see the level moved and the ball in another position, but then the game seems to think the ball is somewhere else.
