as Ghost said, Once you're caught is Considered a Game Over, the Struggles are RNG based, and is pure luck if you're able to get the pred to vomit you, using sound to locate the Pred Works BUT is a guessing game, you can't tell exaclty where they are at, if they are above, underneath or same level as you, and that's something you manage over the experience you gain as you play and if you're spoted with BELLA, TULPY and SATIE, get out of sight as quick as possible and sneak.

I've made well over 50 attempts at this and can't beat Bella at all. No strategy works since she hears the keys drop and can see me from the other side of the map instantly and sees me through walls when tracking me. Add the RNG making escape impossible, and it becomes BS. I like the game, but the preds have a ridiculous advantage that makes it outright unfair. I've also read about a nightmare mode and can't find it anywhere. Is it an unlock?
I was hidden and crouching behind a solid wall in a bathroom after evading her when she saw me from the other end of the hallway and still ate me. I saw her belly since she ate a student and nothing else when she spotted me and despite the fact I was crouching and hidden she still ate me even though I was well outside her view when I hid. For some reason she sees me through walls after I get spotted and will always catch me even if I should have obviously escaped. Not to mention more than half my attempts had all apples behind locked doors that had a key for them behind a locked door. I'm fine with RNG games so long as there is leeway for mistakes but the RNG in this puts the player at a massive disadvantage and unlucky people like me are basically never progressing or unlocking anything. I like the game a lot, but the preds can see me from way too far away and only give a hint if they are very close.
