I like how you posted the code.
The game is ok, nothing too exciting, but one thing tht I thought was really cool is how you have the code open to the public. I've been trying to learn actionscript on my own, and I think that having an example like this will give me a lot of ideas.
two flaws
The tunnels aren't too special, just two colors. and the absence of music kinda sucks the fun out of it. but overall i thought it was fun.
Nice game
it's a nice game a bit hard. i had some probs ther first times i tryed it in the first lvl. 1 thing that would be great to have is a map or a % to see how much more you still need ot go for completing it.
