I've googled several times over many months and can't seem to find the comic again. I read some of it about a year ago online. It featured God (abrahamic) as a black dot with Satan/Lucifer as a red dot with horns. Other gods showed up as different colored dots with various minor embellishments as other characters.
Needless to say, the dialog carried the strip and was pretty well done satire. Unfortunately, I don't remember the author. The devil had three or four kids, one was named Lucy. At least one turned good. Various religious pantheons got involved including Egyptian, Greek/Roman, Hindu, etcetera.
There were multiple attempts to overthrow God, some led by Satan, others by the other pantheons.
