ok there are alot of people confused with 17, this is how to do it
you first cut the top little bar into 4 sections and have them slide down, then, when the balls rolling, you use your last cut to level the ground so that the ball can just push the rest out of the way =D
my score was only 682 wa!
great great game. the thing is, all the programing "tequniques" you used i could have easily done. but couldnt of made this game... cause i dont have the mind of a genuios idea maker(like yourself)
best contraption for 4 balls i did it before i saw all the rest like it but mine is still beter than theres!
