After getting back from holiday (and recovering from), progress on Rescue Squad 2 has been nice and steady, with lots of little tweeks and additions making it into a more rounded game. Most obviously I've drawn a handful of new sprites required for the new features, and to make the levels look more varied.
There's a few different types of boat, including the large cargo ship which you'll have to pick up cargo from in some missions. Currently they don't move but I plan to give them some basic wandering AI in the future, and you'll have to keep an eye on them to see if they get into trouble and need rescuing.
Buildings now have "needs", and will only accept cargo of certain types. Most buildings will accept food and medical cargo, but the new hospital is where you'll have to take the injured people you rescue (rather than unhelpfully ditching them on the nearest oil rig and heading home). Buildings display what they're willing to accept in the little speach bubbles so you know where to take things.
I still haven't figured out a good way to do animated waves and ripples along the coast line though, which has been bugging me for ages.
