Such a unique and insanely confusing experience, but that confusion is what drives me to play honestly. There's nothing much I'd change about the core gameplay aspects, but there are some visual improvements I think you could make to really enhance the experience.
First of all, try to avoid applying a pixelation filter to the labels positioned in 3D space. It made them incredibly difficult to read at times. Additionally, the camera can be a little janky at times, and kind of freaks out when you tab out (I personally think this could be better as a windows / linux build rather than a web build once the jam is over, but it's understandable to focus on a web build for the jam).
Finally, find a font! Find some nice, legible, sci-fi font to use. Correct me if I'm wrong but you seem to have just used the default Godot font, which I think detracts from the vibe you were trying to convey here (though that's just personal opinion).
An overall superb submission to this jam and a game I could see having success going forward!
