Old,but...
I think it's a better idea move the bars with the directional buttons.

Play ping-pong with pink comets. 3 levels. [Level 1]: Learn to tango with a gentle-moving comet . [Level 2]: Practice with a medium-speed comet. [Level 3]: Challenge a high-speed comet. Game can be personalized to be shared with loved ones/friends - please check information in the game :)
Click to select one of the 3 playbuttons. (First time players are advised to start with "Learn to tango with the gentle moving Comet"). Then click on the semi-transparent green areas, moving the horizontal/vertical bar to block the pink comet. (The pink comet is very generous in letting you win easily some basic points :)

Yes, it can be a better idea moving the bars with the directional buttons. But then, as I want to cater for tablet users also, that is why the use of mouse clicks. Thank you.
