Tip 1: some of the entities have some approaching themes, like footsteps, heartbeats, or theme songs (like the partygoers, when they're close to you you can hear them singing "daisy daisy give me your answer do")
Tip 2: save stamina, it will be useful when you are being chased
Tip 3: this tip is very useful in level 6/level 8/level 9, you have to use headphones, listen very carefully and don't despair, that's because the area is VERY dark and you can't know where's the entities are and where they're going, listen very carefully will help you VERY much, if you listen carefully you may know where the entities is, don't despair is very important too, because if the entities sees you, they will chase you automatically, so DON'T DESPAIR
If you follow all the tips i show, maybe you can pass every level of my backrooms game
