The sound of the cicadas and the sound of the sea definitely reminded me of Greece! 🌊 Combined with the sculpture, it also gave me a sense of Ancient Greece. These two elements, together with everything else, made this experience something "I will remember". I also loved your creativity with the riddle!
I struggled a bit with the keyboard shortcuts. Since there are many different keys to press (M, I, O, E, X, H) it would have been more intuitive if movement was controlled with the arrow keys (fast mode) instead of WASD. This way, the right hand could be free for movement, while the left hand would handle the other functions, making the controls feel more comfortable.
Suggestion: I would love it if the door opened more smoothly, and when the lights are turned off, it would be great if the overall lighting in the room was dimmed even more, so that the shadows could become more pronounced and create a more realistic effect.
