Hey my friend,I think that if you updated a fixed,better or more smoother version you should delete the previous one
@Labyrenight Not sure,but I think so...but,believe me,the most fair thing is to delete it cause is the same level,fixed or improved,but in the end the same....don't you think?
I agree with @delator77 - I too had no problems with the balls falling. I did have one hiccup. The Zs, after the third ball drop, bumped in the corner for a while and then luckily one got thru to carry on. This can happen so providing some control below would be best. Thanks for sharing.
