I agree with Radras2. Level 26 is impossible. It is a giant quantum jump worse than 25 or any of the lower levels. I tried it for months and finally gave up. I occasionally go back to try again or play a lower level. If there were a way to skip a level, I would rate the game higher. I paid money to have some fun, not enter a global competition.
Oh, by the way, *very* addictive until you hit the wall at 26.
