Quick addendum to MrCranky's comment about the shipyard: I added 8 warriors around the back corner at wave 18 and didn't lose any lives that wave. I only had 4 lives remaining when I won, so this might help you if you're struggling.
ummm....beat moric the second time....then some countdown thing happened...I've looked all over...but I can't find a way off of the ship....is there some kind of conclusion to this game...or am I just stuck?
