Thank you! for the kind words.
I considered the monster's swinging at you with their BIG... MEATY.... CLAWS! as a form Violence. And the monster's intestines are showing which is a form of blood and gore. (Though I get how that's abstracted when everything is green) But I do agree that it isn't much which is why I gave it a T rating rather than M.
Also, there is only one ending. I'd say I didn't have time during the jam, but really I just didn't consider it for this project. The next one perhaps. ^^
