A few of these are most likely skill issues or just poor luck happening repeatedly. I really shouldn't be playing for several hours on no sleep for a few days and slightly drunk, but I'm an idiot who keeps screwing himself. As for the see through walls and tracking my location even when not being chased, I was actually spotted by her despite her being practically behind a corner on the opposite end of the hallway and going upstairs to the washroom and hiding. She honestly should have lost me since I hid in the last stall crouching, but she still ate me. There was one time I was hiding behind a pillar in a room I was in while sneaking immediately open hearing faint footsteps and she entered the room walking right up to me and insta gulped me. No chase, no gasp, just gulped me instantly. I'm pretty sure she isn't supposed to walk towards the player if they are hiding properly and didn't run near her like she has with me more than once. As for the RNG I finally managed to escape her stomach once and if I were to put a percentage based on my fails to success, it would be 0.3% chance. I'm a very unlucky person.
As for her speed being 25% faster then the player. I did test it on a few runs that I got spotted on prepose and did the math. I'm fine with her being faster then the player, but 25% is a bit much for a character who is supposed to be the slowest. 10%-15% instead of 25% faster with her being about 10% slower then the player after gulping a student isn't an unreasonable request. She's just a bit too fast based on what her profile says. and her field of view is a bit ridiculous for such a small map and some hiding spots such as behind pillars don't actually hide the player from the preds Like they should if she decides to check the room you are in after stopping right outside. and as for her becoming increasingly slower I had her eat 2 students and she wasn't much slower than the player. I think it was a minor glitch where she didn't fully register the second prey she ate since her belly only grew to the size of 2 prey after swallowing me.
(Edit) I'm well aware of my luck with apples being that bad since if only 4 spawns for me they are usually all behind locked doors, but if 8 spawn I usually get 3 in non-locked rooms with 1 on the cafeteria and since the kitchen is almost always locked I at least know where one is should I find the key as fer her sight I was sneaking on the opposite side of the hallway I saw and heard her start running despite her not looking directly at me a few times. I do like the game a lot and the apple mechanics are well done, but how long she's sated by them is about 3 seconds which is just too short in my opinion. I've also been pinned in a room by her a few times since she likes standing in doorways after taking my apple.
