I couldn't find one, but it wasn't difficult for me to get all of them. The only slightly hidden one that you might not expect is when you're moving on the round spinner, there's a suspicious looking region up from left-most part that you want to maneuver up towards.

i want to get 100% on chapter 6, but i can't find a walkthrough for that anywhere! does anybody know where i can find one?

well at least you're honest

Because the game was too hard so I quit it :D

why did you stop posting these, I really need help on the later levels

chapter 4 is up

New video is up thanks to Raatho :)

I'm close to 100%ing all strands and DNA collectibles, hit me up if you need help.

Yeah guess i'll post a video later. This game is haaard :O

The strand in level 1 is right at the start - there's a pipe above you and you can crawl up the right wall to get a foothold.
