I'm getting very aggravated at this point. I beat Challax, got the Electroshock helmet, and saw the last cinematic for that planet. I'm pretty sure I traveled to the Dayni Moon but I either had a low battery or shut it off after that. Now as I go to play again, I didn't start at Dayni Moon but rather Challax and if I try to go through the level again to get to the next "planet" I can destroy the dropship but then the bridge doesn't rise like the first time. I don't want to have to start over. Is there anything I'm missing?

me too it sucks i let my 7 yr old brother play it and next thing i know im stuck in challax

When you defeat the dropship a second time, instead of the bridge appearing a teleporter appears on the platform you fought the ship on
I think you must have missed it
It's the best I can do for now.

Yeah theres probaly a teleproter on the ground or something like that
