101 is not that hard. As mentioned before use the 30 gold traps to block the path. I used bees nests and logs/trees to move the pirates back. Basically you build a maze that pushes them back at every corner. Later I replaces the initial logs I used for blocking with explosives. I then sent all levels after 50 in a single bunch (laaaaaaaaaag). Won it, no lives lost. Too lazy for a video though ;)
