I'm crazy busy with Real Life issues at the moment, which means I've not done any hobby programming for a while. [sad] I'm going over the comments for Rescue Squad at the moment, so at some point I'll be going back to that to expand and tweek it somewhat. Top of my list is more variety in the basic gameplay - mostly changing the victory conditions and adding new elements like damage and fuel. Adding better feedback about your state - like your cargo - is also planned. As is some graphical tweeks like shadows for building and rocks, ripples on the surface of the water, and maybe some particle effects.
