I hope you can zoom the camera out a little bit, I couldn't see where he was landing when he fell off the cliff

Don't mean to sound negative but I'm pretty sure 3rd parties had a positive reaction to the wii u, until it released. 

Mostly because it was more powerful than the PS3/Xbox 360, and the other 8th gen consoles wasn't announced yet, so all they've got to compare the Wii U too was the 7th gen consoles, thus it had a positive reaction

I was more impressed by how accurate he got the animation and movement of Mario compared to the N64 than the fact he's on a different game engine.

But... This guy claimed to have started the Mario 64 remake Feb 2014, got people to give him money through patreon and the only actual progress he's seemed to make is smoothing out Mario's animations/movement, made him prettier and put him into unreal engine 4. He might have more to show on his twitch but it doesn't seem to have any past broadcasts so I can't see anything.

But nintendo has already made a ton of digital only games?

Lets see, he promised a Wii U version if we gave him more money, Nintendo fans gave him more money, then he says he couldn't make a Wii U version... Pretty sure they don't like you either.
