That is interesting. It is amazing how creative OoT streamers are getting.
I think my favorite is Runnerguy2489. One of the best OoT 100% runners, beat the game twice while blindfolded without glitches (second time was 100%), and some other silly stuff. I think the only thing that could compete with playing with an ocarina was playing with TAS Input Tools. Having to move the analog stick and press/hold buttons with the mouse is almost as stupid and hilarious as this.
I hope MonotoneTim finishes this and claims world record.
