Thanks for your feedback.
I've mentioned this in discord already, but the reason why the platforms don't work is because you are using PowerPoint 2007. From experience, despite all the features introduced such as advanced shape effects, the new ribbon design, etc..., 2007 is garbage.
In particular, whenever something is given mouseover functionality, and is given a path animation, the collision for the mouseover function doesn't move with the visible shape. This is fixed in 2010 and on.
That is why I stated in the disclaimer that PowerPoint 2010 was the minimum version required for the game to run properly, with 2013 and later being recommended.
Thanks for your time anyways. Sorry you had issues.
