I cannot find double jump. I'm in the second zone, the green one. I've been back through every room. I have the water proof, the dash, and the slide pack, but can't find double jump...
The red zone was not that hard for me. Though I should add I took long enough and died enough that my final score was negative. Not that I care about my score, though admittedly that does give some replay value to the game. But I don't see why everyone is complaining about the red zone. The three robots died in only 3 tries, maybe 4.
