You play this game to get good at it and become #1. No princesses, no vengeance, just you and your skills. Considering power-ups: green heals, pink doubles shooting speed, and cyan makes bullets bounce (which you might not want). Enemies can take advantage of power-ups too. I put this in the game's instructions as well. Thanks for the tips and cool you like the game!
