Added help text to my physics based tower defense.
Alright so http://joshv.itburns.net/WebAttempt.html has been updated with some help text to help guide users. If anyone finds it too terse, confusing, or anything at all, feel free to let me know!
I've also updated my path planning with a minimal turn radius (http://joshv.itburns.net/RadialAttempt.html), fixed a bug, and some other general performance improvements. I still need to add the width test, as you can pass through diagonals, and the routes will cause the object to penetrate the walls on the sides.
