Look, you have to understand that game development is about you sharing concepts of idea in a correct format (Example - I can draw a circle and say it is a human head, but no one else would think that, because they would see a circle).
The main job of a good developer is to deliver the context of the game in a way so that the player can easily understand. I started the game with no instructions, no context, just opened the door and the killer appeared right in front of me (5 times). I managed to escape the killer for a while, but it would still catch up to me and kill me (25 times, I went through that 25 times). When I tell you that the design is not great, it is based not only on my perception, but also the experience with thousands of games, that I played and more than 30 games, that I made (I am a game developer, like you).
All I want is to have a great time and also for you to make this game work. If you don't want then, fine. But listening to people, who are giving you legit feedback is part of this.
As a novice developer, it is difficult for me to understand what will be understandable to a person and what will not. But despite this, I try my best to make the mechanics of the game as clear as possible, so that the context is simple enough. So I intentionally didn't add any extraneous sounds to the background to emphasize the silence, and I also intentionally made the sound of the door opening loud enough to give rise to the idea that anything that makes a sound is dangerous. Perhaps now my hints are largely incomprehensible to people.
In the description, I described in detail (in my opinion) the basic rules of the game, I hope this will help people understand how it works. Of course, I understand that everything in the game has to be mastered in one game, but due to my limited experience, I'm not capable of it yet.
