I would like to mention that the final attack is even harder because the hitbox on the bones is a little bit messed up... either that, or it is on the soul. Either way, the hitbox is even bigger than it was supposed to be and no one bothered fix it because it is still technically possible to beat it. I know this because I can get to the final attack almost every time, but I was once in a server where someone beat HardMode Sans after I died on the final attack. One last thing. Love how this hardmode is easier to get than Hardmode Insanity and is significantly easier to get too.
