@predeath: each heat producing element spreads its heat evenly among all adjacent elements. in your example each heat gen is spreading 600 to the left and the right. the central generator is recieving 2x600 > 800 and will explode.
I just re-rated this game to 1 star.
Bringing up a teaser game on Kong and "force" you to visit your own
website to play the full game is bullshit.
Kong should remove this game here completely.
