My Impossible Level is possible but you need the trick to it. beat this to learn it. (might help you on the real levels as well)

It was great and intense, but easy as well. I got all 3 badges on 1 try and that was when i started playing. You did good on it though. 5 Stars and Fav'd
Xepter well, yes you keep your achivements, but thats only in the Menu. If you quit and try to continue on, you will have to collect all the achivements again and unlock all the levels again. I think THATS what fredrid06 means.
actually, i like it, but theres just a little thing that should be fixed. The shaking. It messes me up everytime. Either make it shake less or get rid of it.
