Hah! Even something strange happens in this video...
Check the 1:59 timestamp... The Kid screams but is somehow able to grab the ledge. I think first the game checks if Kid is going to fall and then plays the scream sound, but as the Kid is two floors above, he can grab the ledge. Same thing happens if the Kid lands on the guard and even if he should die, the game keeps him active... Wondering if that can be fixed...
