i learned. i defeated lvl 9
it depends on giving accesoires right and
building bunches of lvl 6 combined with 1slow 2stun 2confuse (all can shoot on 2 ways)
and think which element stands where.. range is different. so the short ranged stand next to the second way
some instant kills at start, one bomb plant in the second bunch of mushrooms
teleporters at the end
125 lifes required
