Celeste played using a custom rock climbing hangboard controller

Here I was thinking Celeste was enough of a challenge as is. Now someone has gone out there to prove that you can make the game even harder! Redditor Jwhops has put together a custom rock climbing hangboard controller that he can use to actually play Celeste with. Give me a pair of Joy-Con and I can do just fine. Give me this custom controller and I couldn't make it past the first screen!
