I like the uniqueness, but some bad points as well
Good Points:
I liked how it was in the style of a game; it made it more interactive and interesting than the 'left and right arrows to toggle cursors' style I've always seen.
The animation was very well done. Also, I enjoyed how some of the red and green 'lines' wouldn't form a circle and would simply fall through the play area. Kept it interesting.
Bad Points:
Though it was styled as a game, it was a 'get boring quick' style of game combined with the 'get boring quick' cursor flash. Though it wasn't as 'get boring quick' as the two would normally be on their own, it was a bit long (200 cursors to see) to finish without getting bored first.
Some of the cursors were styled in a way that it was difficult to tell where the actual cursor itself was. This made it difficult to catch the green circles.
Finally, when a cursor had a tail or some sort of thing going away from the cursor itself (of which there were many), if the tail hit a circle, it would count that as a hit. This hindered me many times when the tail of my cursor would hit 3 or 4 red circles one after the other.
All in all, I like the uniqueness, but it is still a boring genre of game (which is no fault of yours) and there are a few glitches. Keep up the good work, though :)
