I was ready to enter and say nah dog, but it really does look impressive and with thought put into it.
The only thing that i dont really like animation wise are the flash when he strikes something and the coins rotating looking weirdly flat on the sides and round in one of the faces.
Evn with the 3 hit system from super mario odyssey i would prefered if in the last hit he would stil be small mario.
Liked a lot the transition from ghe end of the misty 1-1 to the rainy 1-2.
It reminds me of something wario land would do, but mario really needs to step up i this department i think.
But at the end of the day i dont want more pixelart 2d mario, it still looks indie (not in a bad way, but i prefer if nintendo didnt go this way with future 2d mario).
Now, what 2d mario REALLY needsis being "cell animated" to make it look like Kotabe's artstyle.
Becuase fuck nsnb artstyle mediocrity, and while better (and wouldnt surprise me they went this way in the future) the 3d world artstyle in 2d still have that generic air that im not a fan of, something that a feel similarly with Universal's SNW. Its incredibly safe and generic, though it can change by making crazy looking stages like the best ones from 3d world instead of the same grass, desert, snow, lava shit they do for 2d.
Kotabe Nintendo, KOTABE!!!!
