bruh, I found 2 random endings just by goofing off, 1 where you start randomly floating up after leaving your house (still don't know what I did) and 1 where you shoot that gas thing and you blow yourself up
It's some weird bug with the gravity code. I tried taking shortcuts cause I was like "oh the player doesn't need to jump" then that floating bug popped up and I gave up on trying to fix it so it's an official ending
