An interesting game is great visuals. Losing more and more vision and control as you progress through the maze is pretty interesting, though, it can get pretty tedious.
What was with the enter the password thing though? There was no place to enter text. Additionally, is the password that word in the bottom right corner? It feels really bad to get that far and then find out I'm screwed because I didn't memorize the title screen.
I loved that the instructions were given with code. I found it hilarious but that's because I'm a programmer. That kind of tutorial could be too obscure for other players.
