When you stated at the ending on creating nine coins and nine platforms. The coins were perfectly on the platform.

How am I suppose to know the exact coordinates to do that? Am I suppose to know that yet?

Hi Angelo, I've just finished the same task. I added all the platforms first and then placed the first coin on one platform, which was pretty much a game of trial and error. When I had the matching coordinates I could apply that to the other platforms, like: add this amount to the x-axis and decrease that amount from the y-axis of the next platform to get the coordinates of the next coin and so on. :) Hope this helps!
