Took me about two minutes, first try. Finally, something I’m good at! Too bad it’s so pointless. 
It took me about a minute or two as well. There was one hard part where the movement of the balls was random (or it appeared to be random anyhow).
The end screen is more than worth the time it takes to play.
First try, but I have a laptop. The teleporting-balls level does repeat, but the period is pretty long.
Took me maybe six or seven tries, most of them to get past that level right after the final checkpoint. I don’t know why that one seemed hard.
I officially suck. It took me 2 days to win.
