Simplistic, but nice.

I played up to a score from 220. Some of the later random colors were nearly black, so I missed those balls most of the time. After a certain time no more balls spawn? I expected it to get frantic, but it didn't.
Also, this would heavily benefit from a few sound effects.

Hey thanks for the feedback, I really REALLY disliked this after posting it, I felt it was certainly not my best effort at all. I ended up taking it down. I plan to try a lot harder next time, and again, thank you so much :)!
