wow... been a while since i played a "mouse maze" game. and you know why? like everyone else is saying, you should block mouse clicking to get past walls. but, what makes these mouse games great is to include MOVING objects, so that it adds to the challenge then just tediously and slowly moving through a passage. Examples: just some spinning thing, some big object coming behind you (every one loves the Indiana Jones scene!), and platforms where you have to stay on to be safe.
