Thank you for playing! By intro do you mean the first two or three loops? If so, I do plan on making the second loop stand out more to make it less repetitive. I plan on adding background music after the voting period!
The thermostat is modeled after a real one, but it's simplified down for the puzzle. You have to set the temperature to the correct number and push in the correct set of bottom buttons. Interacting with the TV is the clue to finding out how to do the puzzle :) I recommend you try again after I update the game!
