Great work! Very few critiques....
Great work on every aspect in this, this is without a doubt one of the best sprite animations i have seen. Throughout it was too easy to see how much effort you put in.
The graphics were awesome except when you did that thing with the characters' limbs. You made them striaght and rigid, and it just looked really awkward to me sometimes. But the sprites that you created blended in with the professionaly made ones. The detail in everything was amazing, you seem to have tried in every little thing. The backrounds looked great too! The style of this was pretty good. Other than that one lapse in the graphics i talked about your animating style was awesome. The whole feel to the movie was well done. I liekd the idea of there being like a Dark Mario, and the intro in mario's dream was a great addition. The sound was great, nice sound effects, and great choice of music. There was a lot of violence, and i needed some of that.
Overall this was really well done, this is in my top 5 favourite sprite movies, and i have seen quite a few up to this date. Make more in the near future! 4/5
