Inspired me to become a 8 bit spriter
The preloader was welldone
Bad points:
Very Unoriginal
Made mario's front wrong
Bowser's mouth didn't close once when he was in the koopa tank
Part of the block tower is missing in the beggining. (A small hole)
At the end, mario kicks the chain and part of the ground gets missing.
At the end the bridge doesn't fall like that!
The moves were the same all over! There were only like six moves that mario used
The goombas fly so quicklywhen mario hit them! Use some physics and slow down how they bounce away!
The flying koopa was 16 bit! Why don't you even at least recolor it 8 bit?
Bowser's front view was drawn bad.
Mario didn't spin when he was spinning bowser around. Not even frontly!
Why did you make mario stand on the yoshi! He didn't even fit on yoshi when standing on it!
Why didn't the blocks change color like in the game?
You didn't do the back view of mario when he was spinning in the air! You just made the side view!
The bridge didn't fall right away like it should've!
Hope I helped! This movie was cool anyway!
