I just finished playing the demo and wanted to say congratulations on creating such an intriguing atmosphere. The visual presentation and especially the sound design are excellent—they really kept me curious about what was behind each elevator door.
Personally, I found the gameplay a little too passive since I was hoping for more interaction and exploration. However, I understand that's the experience you wanted to create, and I respect that artistic choice.
If the full game expands on this concept with more player interaction while keeping the same atmosphere and audio quality, I think it has the potential to become a very memorable psychological horror experience.
Thank you for sharing the demo, and I wish you the best with the full release!
