I definitely had to go out of my way to figure it out from the submission page and there were some steps that I'm not sure most people could figure out. Biggest "hurdle" was having to create an account on the website but after that, i just had to find the import button to use the JSON from the game. There's an on-screen controller which I had to use my mouse for, like clicking A and B and arrows with my cursor, but for a game like this it's not really a problem. Overall not too hard for me but some people might not like it.
