He's mentioned it a few times, but this is one of the bugged awards. At the moment it only counts if you don't touch anything the very first time you play the level... fixed in the update. I'm assuming you know, but you're also not allowed to touch any walls.
I saw you got a response already, but yeah there's a glitch, it will only count the very first time you play a level. And "anything" means all obstacles and holes. Buttons and checkpoints don't count though.
Fingers crossed for a feature from the devs! Now I've just gotta think of one more idea for a level...
Does anyone of you also has this problem? Just go to the download screen and open a game you did not download to view the game information and screenshots. Then try to go back to the list. The Back-link in the top left is missing. You cant go back. You have to quit the game.
Yes the image is missing, but the button still work. We have already submitted an update that fix this and some other smaller things.
We are probably going to select and include our favorite level packs in an upcoming favorite (some don't have internet access, plus I think people would appreciate if their level was "featured").
