It looks interesting, but as a game developer I will make a few comments
The player feels cramped. It feels cramped in the interior, where walls press on you from all sides and even in open space you don't really feel this openness. For first-person games (and third-person games, by the way), interiors are usually made a little larger than they are in reality, precisely so that the player doesn't feel cramped inside. Also you need adjust the camera a little, in particular increase its viewing angle and play with the lens settings. All this will immediately add space and make the perception of the surrounding world more comfortable.
The hero's movement speed is too low. It is clear that there is running, but you want to move faster at a walk.
To interact with an object or a person, you need to come right up close, this is inconvenient and often passing by you simply don't notice that you can interact with the object. It is better to slightly increase the interactive distance. It is also inconvenient that some objects (a striking example is a bed) need to be approached from a certain side to interact.
The logic of the location of the player's response block in dialogues is also very strange.
