@gmacpro I guess so, because this is the first time I use mechanism. By the way thanks for your comment and rate.
I really liked the original idea of this puzzle, and the gameplay was very good! Got me thinking for a while, and it was interesting to figure it out. I want to give you five stars, but I will agree with @gmacpro ,as I also had problem with mechanism sometimes, and the last ball was really stubborn for me, so I will give you only four stars. But hey! You already showed your progress in difference between your previous and this level! I will wait for your next levels to see new improvements! Thanks for the level
