Not sure how you could actually draw on your tv but I did cut out little shapes on post-its and put them on my tv. And it was incredibly satisfying solving that particular puzzle... but that satisfaction was held back a bit when it didn't appear to unlock anything.

Somehow it really didn’t take me that long to just look on the ground. However I’m sure there are other puzzles that are totally baffling me right now that you had little trouble with.
