Good, Except
If you truly want to get a better score in the portal...
you have to put in extra work with making the kills more creative...
take a look at Krinkles style of kills.
Yours are just simple kills on the most part except a few out there that were creative. The one were he stabs him in the chest then cuts his face up was a good start.
This also lacks speed but hey... madness could still work at any speed!
