Good concept
I like the control style. It makes it more challenging to dodge corners and whatnot. I also liked the keys and gates/doors aspect. They made it feel like a more complete/full game. I see where you could really get complicated with your mazes, which is cool. I've never entered a contest on here before now, so it is cool to see the other entries and get a view of what we're all up against.
Good luck in the contest.
