cant get enough of this game, best try 67 on hard, 50 lives on level 66.
build order - dart monkey, then spam spike throwers till about level 13 and sae for a cannon for level 20.
from there just spam more spike throwers and a couple more cannons, make sure you build close and get a tower to get jungle drums, didnt actually buy monkey storm till level 60
