Medals didn't work, too many easy solutions.
Overall, this game was very easy. Clocked it in 10 minutes. Very good physics engine and an impressive array of objects to be used for different purposes, but the toothed bar was a little unnecessary. Amazing to play and try to find the simplest solution but simpler ideas would be nice. How about a zone instead of a bucket? Also, sometimes the ball would go into the bucket and stay there, but not finish the level for 3 minutes.
Solutions and the link to levels 30-35 do not work at all. The advertisement never ends.
