Learning Game #2: Playtest

I have developed a prototype for the game, and hopefully you (the game dev community) can help me out with a little play testing.

The game rules are very simple. In this prototype you need to make sequences of 6 circles. in order to make a sequence you click on a circle, and while you are holding the left button down you are able to move around adjacent circles and color them.

Only sequences of 6 circles are allowed, so if you do sequences with longer or shorter amounts the computer automatically will erase what you did. The goal of this level is to get 9 sequences of 6 circles.

Here is the game, please share your thoughts and ideas, let me know if you are able to get to 9 groups, also let me know if you feel it is too hard or too easy. Thank you in advanced.
