Your demo got me very excited! I've been studying the demo and trying to apply it to a 3x3 grid of my alphabet tiles.
I have a few questions: are the columns and rows in your demo moving in unison because they are all basically duplications of a single sprite? And also, If I'm using nine unique sprites for my 3x3 grid, is there a way to establish collision behavior to "push" the rows and columns of alphabet tiles?
I'm very appreciative of your help. I'm determined to figure this out, regardless of how much time will be consumed. I've already spent a laughable amount of time getting to this point!
