I really wish there was a way to restore your units to full strength. Gets really annoying when you have to keep buying new ships and upgrading them, then just lose that investment when they're eventually destroyed. Killed the game for me. Also, the controls got buggy when I used the "wind blow" ability when veering away from an island. It would put my ship's shadow against the shore and wouldn't let me move it. Would love to see an improved sequel, though.
