This is Rewritten Skeleton's Under3rr0r fight, good luck because your gonna need it Controls: Undertale controls, nothing new key for first attack (since people are getting confused by it): they make a + then an x a couple times then its both combined, there is a spot where they don't actually hit you though.
this uses the same engine as Soon Enough which you can play here https://scratch.mit.edu/projects/1257893703
