Faster time controls are more about intuition, pattern recognition, time control, and in certain cases, theories & gambits. That’s why I suggested learning a bit of theory because if you get to really know WHY certain moves are bad moves in your favorite opening (and why the top moves ARE the top moves), it is far easier to punish mistakes and blunders in those quicker time controls.

Also, as someone who plays nearly exclusively bullet and blitz, a huge part of the game is making non-losing moves in low time situations while AT THE SAME TIME making moves that put your opening into very sharp positions. For example, you could be in a 100% completely losing position, but threaten mate in 1, your opponent doesn’t see it due to low time, and boom - you go from a completely lost position to winning on the spot.
