This worked for me "The first one was good, this one even better. For the hard badge, I went with Straight Pattern and Fixed Motion. I kept reseting until I got a yellow madness upgrade right into the first wave. I got barely 5,000,000 points at the end. Good luck to the other players. Thanks for the game" (By PloftKaploft)
I see no particular upgrades or new stuff in this game. Its Pyro 1 but with more levels, If you could add more things like water, flame, bouncy floors would make this game better. 2/5
