I'd like to preface this rant with a warning, that I normally over analyze games and try to suggest ways to improve them. Honestly after what I just sat through I think it may be best to just completely start over.
There's no atmosphere, just randomly crashing from one object into the next hoping that eventually, the game will tell you something has happened and allow you to open the next door which inadvertently leads to another very basic jumpscare.
The prebuilt assets within in the game were used effectively, in the future however maybe try to include a larger focus on story and less of a focus on trying to "Gotcha" the player.
Hope this helps you improve.
I also do this for fun.
