The humour is good when it's original and the mystery behind 1000 is intriguing. Not finished with this version of the game, but I have a feeling I may be close.
Also, holy fuck, 01 Ghosts I was the last thing I ever expected to hear in this game. Hearing anything Nine Inch Nails in something like this would throw anyone through a loop.
Either way, I'd give the game a solid 7/10 compared to the other games I've played similar to this one.
EDIT: For those wondering about the song, it's from an instrumental album named Ghosts I-IV (now I-VI with the release of Together and Locusts) created by industrial rock group Nine Inch Nails, more specifically Trent Reznor and Atticus Ross, the same people that scored movies such as Gone Girl, Girl with the Dragon Tattoo, The Social Network, and—more recently—Pixar's Soul. I'd recommend checking their whole discography out if you enjoy industrial metal/rock, synthpop, and soundtrack material.
