Ugh
Where do I start...
As far as I've understood maze games, they're cool because they leave you to make a decision to where to go. There are lots of long corridors here and that would leave the player bored waiting to get to the end of the corridor. You don't get to make decisions on where to go if you're in a hallway. If you wanna do another maze game, be sure to make lots of forks in the path. The only real reason why I could stand waiting to get to the end of a corridor was the music.
There are also two bugs. One bug is that if you were to move 'sideways' while moving down a long corridor, you snap back to the grid. The other bug, is that if you were to bump into a NPC, on a 3-way intersection, your position on the grid would be off, so you would end up trying to bump into a wall when it would look like you're aligned with the grid.
Also, the mute sound doesn't work with music, but only SFX. Is this on purpose?
I also found and gray-ed all NPC's, and it seems that I'm stuck with nothing to do. Damn.
But pretty much, the main thing that wouldn't make this game as awesome as possible, is the maze design. Waaay too much waiting especially if I wander into the bottom of the map. Waiting isn't fun, bro
