Ok, so firstly, I'll admit that I never tested touch actually working on the previous release. Hopefully I will at some point. Nevertheless I realised it would have had a bug, so fixed that. Maybe. It's still not tested.
Anyway, on to the new stuff. For this release I have:
1. changed the way the ship chases to make it less aggressive.
2. tweaked the placement of the help text
3. added a new soft waves setting, which is to become part of a more managed wave system, it's off for this release mind...
Here it is: v6
