So, after a few minutes of playing my computer shut down: just turned off without warning. I turned it back on and started the Librarian again. I sped through what I knew, and got further... then my computer turned off again.
I let my computer idle for a while before without starting the game. No problems came up and a malaware bytes scan detected no problems. I'm not sure what you might need to diagnose whatever was going on. I thought someone here might have had a similar problem.
Anyway, I watched one of the videos below instead of trying to play. I thought the atmosphere was fantastic, and the pixel art great. I'd love to see something like this in a longer, less linear format.
