I got sidetracked by life for a while. Then I tried to integrate google play services for the leaderboard and somehow broke my Unity project. (Fun times) That kind of killed my drive. That and adding sounds, I found to be mind numbing. I don't like the sounds I have now, I find the saw noise to be too grating on the ears.
Anyway, here's a updated link:
I have an APK if anyone wants to try it on their android phone.
I also got sidetracked trying to optimize my radial pathfinder, I'll post about that in a separate thread/article/post/entry/whatever.
