The game was too slow, realy bad choise of speed for a maze game.

Add to this and the vission losses and the game became a frustation.

Also the scrolling was too jaggy, but too many unity games here are like that so I do not count this one.

On the pros was the explanation in code.

Enjoyment is the number one factor in a game, but this do not means that games must be easy. Means that there must be an illusion to the player that he became better, in action games you usually learn the enemy position and patterns, but you feel that you became better cause you hit them in the end. In a maze game you learn the passages but there is no interaction so the player ends up that he just learned the map and this is ussualy not enjoyable enough to keep the player's interest.

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.
