Short answer - yes
Long answer - Only as part of an ending. When you try to leave the hospice via the front gate, Kransh will come to stop you. If you have high enough strength and stomach capacity, you’ll overpower and eat him. Might be other requirements too.
Man, if there isn’t a guide for this game, I hope someone makes one.
I had a save that got it to work once, so I loaded it up to test it out. Funnily enough it didn’t work at first, and got curious enough to dig into the code to see what might be going wrong. Found the full requirements there, on top of the high strength (which doesn’t have to be max, I got the ending with only four lights lit) and stomach capacity requirements.
The easy part - You need to have eaten at least 6 other people, and it needs to be the final day. The day requirement was what I was missing on my own save - waiting till then got me the ending.
The harder part - You also need a certain amount of ‘insight’ that you gain from discovering secrets around the hospice. I don’t think you can track exactly how much you have in game, but if you can see the crack on the second floor stairwell, then you’ve at least made progress with it.
If you need more help, the dev runs a pretty active discord server for the game. You may find more help there and get some sneak peaks on future updates.
