Got stuck on a level? No problem, there's a walkthrough that a very nice guy has posted some years ago.
*** Notes on Level 15 ***
I guess I changed the level during the development for the mobile app. But I've just solved the level and I can assure it is completable!
It's kinda difficult to explain by text, but let me give you some hints:
1) In the first section, clear the blue doors at the right using all the blue colors available.
2) Clear the green door at the top-left of the screen and save the orange color (you are gonna use it at the last section, located before the red doors group).
3) In the middle section, clear the doors at the bottom (the yellow, green and orange doors sequence).
Well, for any questions don't hesitate to ask!
