I wont say the password but I'll give a hint : the hint gived on the computer talks about a file in it. In this file, something is off with some characters.
You're the first to see that there's a bit more story than what is told ! Why the character can't go outside is told after finding the password. The most important secret is the upper left room (what it means)
I love the concept, but the fact that you can barely see in bat form is really annoying (at least to me) and it adds to the frustration that people already talked about. But overall the game is solid !
