This game works well, but I find the generated mazes are pretty easy, with a main path that has just a few short dead-ends coming off of it. Maybe I just got unlucky with the random aspect, but it seems like an area for improvement."
I'd also be interested to see what this game would be like with hand-made mazes and a little more of a meta-game aspects like better tuned target times or high scores.
Still, this is a fine entry, good work!
