Okay, so if you use helmet on a challenge that says take no damage, you can take damage. It gives you the bonus 500HP on top of your given, I'm assuming, 1 hp.
All right, so Challenge 7. I just did it, and I took a lot of hits. Not sure what was up, but my hp bar was definitely going down and I actually saw myself get hit by bullets. I had tried previous times, but I would die instantly when I was hit, but I just completed it after taking significant damage. So. Yeah.
I've logged over 300 attempts into 1 k + height, and then running out of fuel while that high. Why. Do. I. Not. Have. It's Rob. Medal. It's my last on :((
I'm glad turning invisible doesn't mean anything and I can still get hit. And that I can spam my chaos special like that one title fight guy. So awesome.
Yeah, I beat the guy on round 6, my character loses the ability to jump immediately after wards, I fall down a whole and keep running under the map forever, I can't rewind either or do anything. I've re tried the level 3 times. After refreshes.
