More And Yet More

So, it looks like there is still a lot left to do. I've made a few updates already, particles look less threatening and you can lay fewer mines. The controls are a lot different, too, to support Mac users, but I fear they are not a very good choice of keys. I still need to update the instructions to reflect the new keys. Still a bunch of fixes left, especially collisions. Which I suppose is good because I still have 5 weeks of this project left.
