Hello I watched a lot of speedrun on hello neighbor but I realized that in the basement of act 3 I was doing the glitch with a kind of fake house on the screen but there are a lot of people doing the glitch with a tv I've been on it for 3 hours now and I haven't succeeded once I manage to propel myself in the air and touch the wooden thing but when I land the shadow moves anyway and the fence is there can someone help me on that.

Grab the tv, stand before the gate activated, look straight down and charge a super throw, look slightly up and then release the throw and spam jump.
