Agree with a lot of your Points but...
- Talking bag only works if you get the jumpscare, if you go by the jumpscare and just get back to the starting room from the crash he wont talk, in the original he does.
--??? The Bag does work the exact same Way as in the Original. When you get jumpscared before the Bag talks. If not it won´t. Don´t get what you mean here.- In the "gouge it out" hall, you should be able to see the shadow of lisa following you as you come up the hall
--You can see her Shadow behind you in this Loop, it´s clearly visible when you light your Flashlight at the Walls the Shadow just doesn´t cast through the entire Hallway like in the Original.
- The lisa jumpscare itself definitely needs a little work, honestly would not be mad if in that scenario only it just played the clip from the game. That jumpscare is too well crafted to properly recreate in my opinion.
-- Clearly Nope this one should stay in Real Time, adding a Clip from the OG leads only to the same Issue P.T. Emulation 1.4 has. It totally puts you out of the Game and also this would be a total Nightmare to do on a technical Level. I mean just accounting for every Angle you can get attacked by Lisa... Just No.
- In the bathroom, the door should only reopen if you zoom on the mirror, just glancing at it doesn't open it in the original which makes it more of a puzzle
--Wrong, you only need to look at the Mirror. the Way it´s done here in this Remake is correct, the only thing wrong is you have to wait slightly longer than in the Original.
Here is also some Points you have missed.
Cockroaches are missing in the Bathroom and next to the Radio in the Loop where the Moderator says look behind you.
When Lisa stands in the Hallway and the Light goes out she despawns in the Original Game at the same Time, but honestly I kind of like that she doesn´t do this in this Remake until you walk right up to her.
When Lisa stands on the Balcony you hear some Footsteps in the Original Game even if she in Reality didn´t move at all, must be to signal the Player to look up. She also waits longer before moving backwards in the Original Game. But Credit were credit is due, this is the best Animation of Lisa on the Balcony that I have seen in any of those Remakes only the Original has better Animations, really this one looks really good!!! She only seems to lack some Hair features in this Scene.
Final loop puzzle Issues: The take 10 steps and then stop counter doesn´t reset everytime you make less or more than 10 steps.
The say Jack Trigger is not included it is simply enough to make any kind of Noise while being near Lisa Haunting.
When you play with a Controller you could bring back Vibration like in the Original Game after the second Laugh, just a minor Thing. But of course the flickering Flashlight can stay when you play with Mouse and Keyboard I am totally fine with that.
In the Original Game Lisa can only attack you a single Time through normal Means. This includes the Moment where the Radio Moderator says Look behind you and the two Instances the Loop is infinite (Hanging Fridge Loop and Final Loop). So after you got jumpscared once you are safe as long as you keep the Game running.
Also minor, That Lisa is able to attack you multiple Times in a row is okay in my Book.
In case you didn´t know, There are only two Ways of getting jumpscared a second or more Times in the Original Game.
First: In the two Instances the Loop is infinite (Hanging Fridge Loop and Final Loop) after exactly 51 Loops Lisa will alway jumpscare the Player at the End of the Hallway, this will always happen no matter how many Times this happend before. Was probably made like this to indicate the Player that simply ending the Loop doesn´t progess the Game.
Second: If the Player falls out of bounds Lisa will attack the Player as a Failsafe.
