The graphics are really stunning, I really liked the glassy look on top of the casino machines, it give a really particular atmosphere in this first room that I really liked, and the other rooms really gave that casino feel, beautiful. The only thing that is missing to truly complete this ambience is a music !
I think you could maybe lower the camera blur a bit which was a bit harsh, and maybe give more contrast to the first message asking you to press space bar, it took me some time to read it correctly ahah
Its overall a great experience, well done !
