The faries refill your "Time Stop" gauge (hold [Z] to activate) and also net you points.
Some pointers: 1. You can cancel out most danmaku (bullets) by shooting at them. 2. Your sight is your hit box. Don't get it hit. 3. The faster to you take down Meiling (AKA China), the more points you get. 4. If you want to be recognized for your score, click on the source link. The 4th option when the flash loads tells you the current standings.
comment #49589 You don't. You dodge them with all the agility you have in your clicking hand. And damn, I thought Lvl 15 was HARD. I almost had Meiling until a shitload of faeries popped up and blasted me. They were EVERYWHERE, I tells ya!
