Nice game. I love the idea. I'd love to see more levels with a variety of obstacles/hazards to avoid. It's funny to see them stuck next to the lifeboats and not get in. :D
It really messed me up a lot to have to click outside the blue circles all the time. I want to just click in a direction to orient the crew and not have to worry about what exactly I'm clicking on. Shouldn't be terribly hard to fix, but important.
Some polish (sound effects, passengers remaining UI, etc) would make it excellent.
