When I first started playing this I was smashing face off keyboard! It is very fun and easy actally ^^ . If your quick at making trees or stones it goes fast. I only use sweep to start off and stack them with poison/stun/frost mix of those. Then 1 arrow I max first with 2 skybound towers! 6-8 Towers per lvl! Then you can save your trees for a FML scenario. Figured out space pauses, big help there :) !!! Great Game.
