ummm so i got the lil pink person and while i was tring to figure it out i attacked back towards the previous screen...... got stuck in limbo (off screen)
made it to challenge 7...... my sniper rifle doesn't one hit kill them most of the time, i had to hit a guy with the grenade launcher 3 times to kill him, and when i tried using the desert eagle it would lag; my shot wouldn't go off; they'd kill me instead a second or 2 later. :( other than that really fun.
