Hey, I just played your game and thought it was pretty cool. I got stuck on the password thing but I would be willing to give it another shot if I got a hint as to where the two missing numbers are. Also, I don't know if you know, but there is a door that leads to nowhere and you can walk off the map.
P.S. As someone who uses unreal engine the print strings for when you try to open a door and you don't have the key kind of breaks the immersion for me.
That is my constructive criticism of your game, I hope you have a wonderful day.
