Under rating threshold (hideshow)
If you made the catching a bit more generous then you could remove the bit about needing a decent mouse. I got to level 12 with a trackpad, and then got very frustrated because perceptually I thought I was clicking in the right place at the right time, but I wasn't catching. Perhaps allow the catch if the ball overlaps the mouse not just when the mouse is clicked but for 0.04 seconds afterwards as well?
