I was waiting to play this game since it was an Unreal editable (sorry, I don't use that engine heh). Once I played, I can say this game was a visual surprise and a truly immersive short experience. I like the color palette that you chose and every element on screen as they look cohesive.
I consider that at least a cursor or a selector for the objects that you interact with is needed. You should add more elements to the gameplay that could represent a danger or a risk to the player and a clear goal, even for the short experience that you had in mind.
Good job!
