Thanks for the comment, man! Funny thing is, some of the "issues" you pointed out are actually part of the game, haha! Like, your steps being loud to make you aware that you're noisy and need to move slowly. Chica has loud steps, but with a "bug" of distance, the excessive loud sounds obscure her footsteps (your footsteps, ambient sounds, etc). The current version already features ventilation ducts, and you can enter some places that I won't spoil, but indeed, her AI is totally random. When she sees you, a random value is thrown, if it's above 50, she saw you, if not, she "pretends" she didn't. Similarly, she listens to your footsteps, and the AI randomly decides whether to check the noise or not. She also notices your flashlight, but anyways, I'll soon release an improved version of the game. I only release significantly enhanced versions of projects, not small updates. It'll arrive first for Patreons, and a few days later for the public (so I can receive feedback on bugs, major errors, and relevant opinions).
