Really short, a bit unsettling, I think I heard of similar concept done before as a social experiment, where players interact with the choice made by the previous person, but I cannot recall it as of now. The main point of the game is the hall69.exe thing. I'm not sure how necessary or what symbolism/purpose does the first part serve.
Overall It's a really nice concept, I do hope it actually stores some sort of database of wishes and they aren't just pulled from an array of pre-made ones. I wish it had leaned more towards the program itself more to be more coherent of an experience however.
