Tips (read the best comments first though). Small bomb method + lots of clicks (necessary in last 11 levels). Small bombs near the start (to prevent lag). (Shift+mash mouse, don't move mouse, start while sending all waves). Focus on clicking fast (I read ppl have rly hi cps, not needed). You can let a dribble of tanks pass through the bombing to conserve money. dw bout a couple that hit your base (e.g. lvl 40 end beetles). Add: poison tower (lvl 2-3) at start, {2 (lvl 1) or 1 (lvl 2)} super towers in corner. x1 speed & no mid-game upgrades/change in bombing (avoid lag). Poison hurts even after green glow stops. Your score v expert gauges progress. At end, with large gaps between tanks, conserve money, sell off towers that no longer fire, upgrade others. Large bomb technique also good for earlier lvls, and not all-waves-at-once possible for a couple in lvl 30+ but small bomb technique better.
