Easy Achievements
The achievements for beating the game on different levels are very easy to collect. Once you've made it to level 5-6 (Cleavage) on Normal mode, regardless of the difficulty, you can go right back to that level at any time. You can then just pick your ship, power up at the start of the level, and beat the boss again. Even though you only fight this one battle, it still counts as beating the game for the achievements.
