For this achievement you will have to complete stage one of the game.
Tips:
- Tap X as fast as possible because your bullets fire faster.
- Pick up as many power ups as you can.
- Avoid the W power up because it skips some of the level so you will lose points.
-During the mid level boss and end level boss you can use a transformation with Y to do more damage.
