Finished it. Interesting game!
**SPOILERS**
After carefully timing deaths and kills for an hour, I also noticed that the music wasn't really changing anymore. So doing nothing after death triggers the ending! A message about the futility of revenge...I was predicting that it would be along those lines, just not sure how to trigger that event until I accidentally did. I think also entering the "hugzone" according to the github messages also might trigger it, and on my first playthrough I didn't get the scripted slowed down hug (I could move my player around as normal, ironically in fact I posed it for the screenshot). But interesting game. Great job.
