I just got all 9 ending but still missing 4 of the extra picture content, sooooo... idk. Overall a very fun consept. At first I found the entire thing frustrating but once I figured out the patterns it became much more enjoyable.
Very very cool. I really liked the atmosphere and the theme. I think I stumbled upon a bug, I don't know how or why this happened but when I cracked the safe there wasn't a hammer or anything. Still had fun though.
