I appreciate games that play with my expectations and offer unusual ways of interacting with other players, and your game was exactly the case. For a moment, I thought I had encountered a bug when the room disappeared, but then I found the crack in the wall, and it was a very satisfying moment. The conversation with the computer was genuinely eerie for me, and I was interested to see what the other player's wish was (although the result was disappointing).
Overall, it was an interesting little experience. Thank you for the game!
