So I was wondering when I first saw the screenshots and was wondering/almost positive you used static images and then this glitch happened :p 
Not entirely sure what caused it.. Happened while I was using the computer (While putting the password in)! Holding Ctrl here also seemed to move the camera!
Found thew game to be enjoyable although I wish the Input bars on the safe code aligned with the total number for the actual code, that made it a bit tricky! The ending was also a bit of a let down sadly, I saw another comment talking about the box thing and completely agree but guessing time restraints? Anyway good work I really liked it :)
