Snake Pass

I tried to do the other video's method for over 3 hours without success.

I then looked around the map, and did an alternate route, going from the pink gate piece to the yellow gate piece.

This route popped the achievement on my FIRST attempt. Make sure that you are playing in time trial mode, and if you've failed previously, quit the app ENTIRELY and reload it from the dashboard.
You can see my route in the video below:

I just did this in the stupidest fashion. I was going to try a method of getting the pink first and working your way towards the yellow via the side walls. However I failed completely fell off the edge and respawned at the checkpoint.

I then picked up the pink again and the achievement popped.

Here's the clip of what happened.
(Unfortunately you don't see it pop but it appeared around the point where I turn away from the top of the tube)


I figured I'd post this so that others might be able to replicate it. Good Luck.

This can be done more easier than it ask. Just go and touch the checkpoint near the pink stone, take the pink stone and then fall yourself off to die and once you respawn from the checkpoint, take the pink stone again. That made the trick for me, and I did it in Normal Mode, so don't worry. This achievement is said to be glitched and hard to achieve, so better do this.

First of all, like other achievements in this game, even if you fulfill the requirements the achievement might not unlock. In order to prevent this, attempt the achievement as soon as you start up the game. If it does not unlock then dashboard and quit the game to try again.

You CAN touch the floor on the way to the first key.
You CAN touch the raised level above the floor level on the way to the second key.

Like "No Diving", this achievement seems to be extremely glitchy. After a couple of hours of trying, I unlocked this on a completely random run that I was sure I failed. I did clip it, though, so you can see it here:



This confirms a few of the mechanics of the achievement, at least:
- You just need to get from one keystone to the next without touching the floor.
- Touching the wall (even grassy wall) is fine.
- I'm guessing you also can't touch the floor for a few seconds after picking up the green keystone. This is very annoying, as Doodle will drop your tail once you do. As you can see, my tail drops at the end, but only after a few seconds.
- The achievement unlocked for me a second after the green keystone appeared in its outline.
- I had a very poor jump in this clip. You can actually jump directly to the green keystone (though I haven't managed to do this without my tail dropping to the ground).
- I started the level fresh from the level select menu (NOT using retry). No idea if this is necessary, but doing this is what got me No Diving, so who knows?

All I can suggest is that this achievement's requirements are bugged and enough attempts will randomly get it for you.

EDIT: As of June 21, 2017, this has reportedly been patched. I'll leave the solution up, but hopefully this is much more doable now.

I'll try to make a video guide in the next few days but I'd just like to point something out, Do not touch the floor doesn't mean you can't touch the floor between the two gems, it means you can't touch the floor on your way to the first gem.

Basically at the first set of bamboo you have to make your way all the way to the green, and then Yellow gems without touching the "ground level" (the lowest floor after the initial bamboo puzzle) and not touching that ground level again until Doodle actually takes the gem from you and fills in the collectible screen. It's incredibly infuriating and tight, with possible leeway given for the tip of your tail touching the ground as you'll come awfully close many times as Doodle is carrying you.

This isn't easy, I thought I'd add my two cents, and good luck.
