My high score is 13!
It took me a few tries to understand the controls and goal, that the claw follows your mouse pointer and you have to pick up teddy bears and move them to the box without getting hit by the fly.
I think the first time I played, the claw grabbed a teddy bear immediately so I thought it was always there and that I was a claw wielding a teddybear as a weapon. At first I was trying to catch the fly and use my bear powers to attack, and that did NOT work. But I got the hang of it eventually!
Nice little game :)
