I feel like the creator was inspired from Danganaropa mainly (a bunch of high school teens are locked in a school and a motherfucking bear kills them in diabolical fucking ways one by one) early flash cartoons, and squid game
So I just forced myself to watch thw entirety of part 1. First thing first it feels like the animator intentionally chose the goofiest laughs he could find in the internet
Second things second I already know he was stroking his tiny chinese clitty while he was animating this
