I wonder how the 5% Attack Bonuses counts. If you dice the maximum possible, 8x6=48, does it mean you get 1,05x48=50,4? If that's true, the Bonuses are ridicolous. I hope Lopdo or someone else can tell me the truth about that.
i am now at level 8 and now i am so bored
you do not need to reset your skills
just play level 2 several times, each you gain 2 skill points
now , at level 8, its so damn easy with upgraded skills that i wont play it anymore untill there are badges and achievements
i am now level 3
so glad i managed to get so far :P
there is another bug
if you press pause and have a break, the burning ones keep on loosing health ;) maybe this is a little help for you
and another idea to pass level 1, the energy towers are really strong against the annoying reds ;)
