Pretty cool start to the game! I like the graphics, the music fit very well, and I like how the game is dialogue-driven. Vicient is quite creepy and it made me want to know more about the backstory.
One thing that might improve the experience is allowing the buttons to reset if they are pressed in the wrong order. Currently, it feels like the game softlocks if you make a mistake, which can be a bit frustrating. Also, the P and K keys felt a bit awkward to use; maybe consider mapping the controls to something more intuitive. When I did get the order right and talked to the door, the game just faded to black, which left me a bit confused about what to do next.
Overall, you've got a solid foundation here. With a few tweaks and a bit more polish, I think this game could be really fun and satisfying to play. Keep up the great work
