Last week Matt sent me to the Magic Pen as payback for Fantastic Contraption, but I suck at drawing things freehand, so I gave up on level 3.
I did, however, manage to follow some links to Button Hunt 3, which I found much more fun.
Apparently the goal is to solve all the puzzles in less than 185 seconds with fewer than 110 clicks of the mouse. My best score was 233 seconds and 130 clicks.
