First of all, excuse my English but I donot English (I speak Spanish).
I do not understand how to make enemies and even huge giants may have a perfect or near perfect coalition (in my case is still just a transparent solid square and others), here I leave one of the sprites I use (some are smaller than this and larger than the other). If you can make a tutorial on how to make perfect or near-perfect sprites coalition event of this size or larger, would greatly appreciate it.

In mediafire just let the picture because I did not find another way to raise it to be visualized without descaragrla. I beg your pardon for this.
