Collectible Cog Locations?

[Gloves]

Let's chat Cogs. I'm going for 100% cogs in the desert right now, and am lacking a single cog. I have those found in the following levels: 3, 6, 9, 10, 12, 13, 14, 15, 18.

Anyone know where the last of the 10 cogs is in the Desert levels?

First of all, a general pattern that I noticed so far:
There seem to be 5 cogs per row on the level select screens.

I think it's more fun if you try to find them by yourselves, or - if you can't find one - move on and return later to search again. Anyway, here are the locations for the first 3 worlds:

Desert: 3 6 7 9 10 12 13 14 15 18
Volcano: 24 25 27 28 29 32 35 36 38 39
Space: 41 42 45 46 48 51 52 55 57 58 59

Edit: Have I been trolled by the devs? ^_^ Yay, I located 11/10 Space cogs!

Troll or feature? :)

Ah, never mind! I thought one of the cogs may be unattainable, but I figured out how to get it.

P.S.: If I talk about being trolled by the devs in a game like this, it's usually meant as a compliment. ;)

Oh I fully took it that way :) I'll be honest it was a mistake but in about an hour or two it'll be a feature! Thanks for catching it.

Hello all, where are cogs location of the dark world please ? :)

For anyone that 100%s this game in the future and doesn't want to search for the cogs in the dark world, they're found in 61, 64, 65, 67, 69, 71, 75, 77, 78, 79
