No I dont think so

Shooting through walls to spawn in enemies, such as in Act 5 of Golden Trophy is not allowed in a glitchless run, but it is in an Any% run. If you do use shooting through walls as a strategy, your run would have to be submitted as an Any%

bru, your shooting though a wall how is it not a glitch

Would it be illegal to teleport behind the boss on gt so he doesn't see you? I've seen a few people do it, and I'm not sure if that's wall hiding or not. It's a bit confusing

i think it counts as an any% rule

@Perfectzzzz Well depends if you're actually IN the wall. If you're not, the boss still will detect you.
