This is interesting, I would love to criticize it on the fact that the "Vikings" are stereotypes but the Ninja Viking was an interesting twist, I enjoyed the fact you showed some form of conflict instead of vikings killing people and nothing more.
Its a quality concept and I would like to see how you intend to expand upon the concept in the future, thank you for adding some higher quality content on Newgrounds.
