u know if u click on a tower and then then move it around the map take it somewhere it can be right click and then left click on the track the tower will now be build at the track :D
peasy just go get rank 30 and u will own em just keeep buying the bana farms until u got 9 upgrade them with lab upgrade and then just begin shopping get like 20 sun gods and you wont ever die if u combine them with sum radar towers
to fight mr worm just buy the dumpster and then the bat and the dumpster dive upgrade fly really high (over 500 in points) and then use dumptser dive and u will go down to a tunnel if u keep holding dumpster dive
here is an advice to get xp hat or santa hat if u want them be 2 then continue to go to newbieland and just qit if u dont get anything then for the most u will win santa but sometimes xp hat's 2!
the best tactic to smash down enemy knight is that you pick the red dude so you start with comet then gather a big army at your castle then use meteor on the enemy knight he will charge when he is nearly at your base press forward and the enemy knight will die in seconds
