full game guide, i beat 39 but then game just ended what are people talking about bonus levels? and how are the max scores so high?

the key is not wasting too much early on that you can't get the good stuff later on. 2 upgraded archer towers and 1 cannon upgraded (all to lvl 3) can hold the front lines until the flyer level where you should add one fully upgraded flyer tower, then you will get the wood to afford an earth tower and then upgrade that once and then buy another later when necessary and upgrade that once as well-- then it is all for saving money until you can get the bottom rocket 2000 dmg per attack wep that can hit the whole screen, just put those upgraded in the center and watch everything go kersplat
