needs ALOT OF WORK!!!!
This sprite battle has alot to be done first off you need to add more motion secondly needs sound effects if you dont know how to do something or where to get something thats why Newgrounds has forums use them!!lastly you need to work on your gore its was pretty cheesy and u need some sort of backround or atleast explain on why there fighting in a pitch black area..and you should look into to explain why these charecters are interacting with each other and why they want to fight each other.
