I KNOW WHAT THE SOLAR PANEL DOES! Put the solar panel's surface pointing to the sun (left-middle of the screen), is saves you from losing from the Efficiency bar (you dont actually lose, just you cant complete the next level until you edit it a bit)
1) Wheres the boss? 2) Too Easy. 3) Can there be multiple cars where you have to shoot? 4) How about more levels? 5) More health for enemies, it took me 4 seconds to beat the last level. 6) More upgrades or Kinds of upgrades. 0.13/5
Single kill: Average. Double kill: Nice for a n00b. Triple Kill: Awesome! Quadruple kill: Owned. 5x kill: Wheres the proof? 6x or over kill: Dont bother with hackin' the game, bub
(sorry for Triple post) or just go to this: ( http://www.kongregate.com/feedback/new ) then you can put the heading on Other Things (or something like that) then type: I havent got my badge on "The Endless Zombie Rampage", what shall I do?"
