Could be better, but I like it.
Very cool; I played it a few times seeing how many greens I could get. Then get hit by a red, lose my score, cry, and try again. I would say that if you were going to do another one make some walls pop up to block the circles or the area shrinks the higher your score is. Some kind of random variable would make the game more fun. Other than that Good job man.
