I checked the release dates and it's indeed stolen. Some frames I noticed that are stolen from you and catoblepas.
I recognized catoblepas's artstyle well at the knife part in his video "peach the Pedophile detective" and many more.
So yeah, I'm disappointed as well.
I loved his art and all, he could have done better.

I guess using nintendo characters wasn't enough for him
