Petition to Rovio
I think it might be a good idea to try to start an online petition to Rovio. There are many times, especially during competitions and tournaments, when the use of power ups is not permitted. on level after level as we're trying repeatedly to get the best score, we see these pop-ups asking us to spend some of our hard-earned money on power ups that we can't use anyway because it will invalidate the score.
There are also the pop-ups that happen every four or five times when you're trying to deadhead a bird and not activate it, showing us how to use the bird.
Two simple solutions.
1) add a tournament-mode button that disables power up prompts for a level. Tapping the button would eliminate the pop ups for that level until the player exits the level. I would say disable them permanently, but we know that won't happen.
2) if a player has more than X number of hours, assume that the player KNOWS HOW TO PLAY THE FREAKING GAME and don't show pop ups demonstrating a particular bird's functionality that needlessly interrupt, irritate, and aggravate.
